Cylindrical roller bearings are one of the most widely used rolling bearings. Most of QIBR cylindrical roller bearings are separate bearings, which are very convenient to install and disassemble. The roller of the cylindrical roller bearing is in direct contact with the raceway, so the radial load capacity is large. It is suitable for both heavy loads and shock loads, also high speed rotation. It is mainly subjected to large radial loads, and in order to improve its bearing capacity, the raceway and roller crown profile can be trimmed.

Cylindrical roller bearings are consists of outer ring, inner ring, rollers and cage. The ring has ribs on both sides. Normally the structure of bearing is that cage, rollers and one ring build up the assembly, and another ring is separable. In special cases, cylindrical roller bearings without retainers can be formed.

The outer dimensions of QIBR cylindrical roller bearings conform to GB/T273.3 "Genera plan for the outer dimensions of rolling bearing radial bearing", GB/T283 "Dimensions of rolling bearing cylindrical roller bearings", GB/T285 "Dimensions of rolling bearing double row cylindrical roller bearings", JB/T5389.1 "Rolling bearing and four row cylindrical roller bearings for rolling mills" and other regulations.

The tolerance of QIBR standard cylindrical roller bearings meets the requirements of GB/T307.1 "Tolerance of rolling bearing radial bearing" and other standards.

The clearance of QIBR standard cylindrical roller bearings meets the requirements of GB/T4604 "radial clearance of rolling bearings".

The dimensional tolerance grade of QIBR cylindrical roller bearings is generally made according to P0 (normal grade) and clearance according to group 0 (basic group). If customers have other special requirements (including non-standard) for size, tolerance and clearance, QIBR are able to provide the corresponding product.

QIBR non-standard customized cylindrical roller bearing

Non-standard cylindrical roller bearing customization is a main part of QIBR categories. It can be customized according to the customer's working conditions or the place where the bearing works. Internally we can optimize and improve the design of the cylindrical roller bearing, which can improve the loading capacity and service life of bearing.

The inner bore of the single row and double row cylindrical roller bearings can be designed as a tapered (1: 2) bore bearing, and the outer ring can also be designed as a cylindrical roller bearing with a snap groove.

Our QIBR enables non-standard cylindrical roller bearings to operate safely and smoothly with precision roller selection and bearing raceway production, to achieve optimum bearing performance.

Raw material

QIBR precision anti-friction bearings are usually made of chrome steel, which consist of about 1% carbon, 1.5% chromium and a small amount of manganese, silicon, and sometimes a small amount of molybdenum.

QIBR offers you a wide range of material options such as GCr15, 100Cr6, SKF 3, SUJ-2 etc. At the same time, some models of QIBR are available in stainless steel.

The rolling element can be ceramic ball (silicon nitride). Due to ceramic is kind of special material, the ceramic ball bearing has advantages of higher rotation speed, good self-lubricating property, and the rigidity is 15%-20% higher than the general bearing, and better high temperature resistance.

Bearing cage

The high-quality cage used by QIBR bearings ensure that the rollers and balls are evenly distributed in the bearing rings and can be rotated properly.

The cage is divided into stamped cage, brass solid cage, reinforced nylon 66 etc. Bearing cages that operate under high temperature or harsh conditions are recommended to use steel cages or brass solid cages, four-row cylindrical roller bearing is recommended to use brass solid cages. QIBR offers a wide range of advice and options depending on the operating conditions.

Type of lubrication

Lubricating oil is the basic lubricant for ball bearings. Previously most of the lubricating oil was extracted from petroleum. Synthetic oils are now acceptable due to improved performance, such as two lipid synthetic oils, silicones and fluorocarbon synthetic oils. In general, lipid synthetic oils have better low temperature properties, lower volatility, and better temperature characteristics and viscosity compared than petroleum refined oils. Essentially all lubricants contain additives to inhibit chemical changes, prevent metal corrosion, and improve physical properties (antifoam, etc.).

The silicone and fluorocarbon synthetic oils that adopted by QIBR have lower volatility and wider temperature/viscosity characteristics.

Radial clearance

The radial clearance is the gap between the steel ball and the ring. QIBR are able to tailor to you based on temperature conditions, interference fit, and misalignment of the bearing axis, required noise level and speed.

Service life and the rated load

The bearing life is the number of bearing rotations before the fatigue occurs on the ring or any rolling element (or the rotation time at a constant speed). However, the same set of bearings will not necessarily have the same life under the same conditions. In this case, the rated life is the number of rotations that 90% of the bearings in this group can reach or exceed before bearing weariness (or the rotation time at a constant speed). The service life of QIBR series bearings are 5%-10% longer than other bearings of the same model, through strict production process, high standard material selection, precision control.

The classification of cylindrical roller bearings

According to the distribution of the ring ribs, cylindrical roller bearings are divided into four types: outer ring without rib single row cylindrical roller bearing (N type), single row cylindrical roller bearing with inner rib (NJ type), single row cylindrical roller bearing with flat snap ring (NUP type), single row cylindrical roller bearing with slanting ring (NJ+HJ type).

According to the number of rows of rollers, it can be divided into single row, double row and multi row roller bearings.

N type cylindrical roller bearing

NJ type cylindrical roller bearing

NUP type cylindrical roller bearing

NH(NJ+HJ) type cylindrical roller bearing

NN type double row cylindrical roller bearing

FCD type four row cylindrical roller bearing

Type N

The outer ring of the N-type bearing has no ribs, and the inner ring has ribs on both sides. It is possible to allow displacement of the shaft in the axial direction to the bearing housing. Therefore, this type of structure is suitable for use as a swim end bearing.

Type NJ

NJ-type bearings have ribs on both sides of the outer ring, and the inner ring has ribs on one side. The bearing can withstand a certain amount of one-way axial load. Therefore, this type of structure is suitable for use as a unidirectional axially oriented bearing.

Type NUP

The NUP type bearing has ribs on both sides of the outer ring, a (fixed) single rib on one side of the inner ring, and a detachable flat ring on the other side. The bearing is able to withstand a certain amount of bidirectional axial load. Such structural bearings can limit the displacement of the shaft in both axial directions to the bearing housing. Therefore, it is suitable for use as a fixed end bearing.

Type NH(NJ+HJ)

The NH type bearing is a combination of the NJ type bearing and the HJ type slanting ring. The NH-type bearing can take advantage of the width of the entire inner ring of the NJ-type bearing to maintain a tighter fit with the shaft. NH bearings are easier to install and remove. And the bearing can limit the displacement of the shaft in the axial direction to the bearing housing. Therefore, it is suitable for use as a fixed end bearing.

NN type double row cylindrical roller bearing

The outer ring of the NN bearing has no ribs, and the inner ring has ribs on both sides and middle location. It is possible to allow displacement of the shaft in the axial direction to the bearing housing in both directions. Therefore, such a structure is suitable as a swim end bearing. Most of the cages of these bearing are lathe-made solid cage.

FCD type four-row cylindrical roller bearing

Four-row cylindrical roller bearings are mainly used in rolling mill machinery such as cold and hot rolling mills and blanking machines. The bearings are separated structures, and the bearing rings and rolling element assemblies can be easily separated. Therefore, it is convenient to clean, inspect, install and remove the bearing.

The FCD type bearing allows the displacement of the shaft in the axial direction to the bearing housing in both directions. Therefore, such a structure is suitable as a swim end bearing. Lathe-made solid cages are often used for this type of bearings.
