Characteristics of QIBR Deep Groove Ball Bearing

● Deep groove ball bearings are one of the most widely used rolling bearings, QIBR deep groove ball bearings are simply in structure and easy to use.

● It mainly carries the radial loads.

● The deep groove ball bearings can have certain of same performance as angular contact ball bearings, by increasing the height coefficient and radial clearance. It has the ability to withstand a certain axial load.

● Deep groove ball bearings are the most common type of bearings in working life. The bearings are mainly subjected to radial loads and can withstand certain axial loads, and have low friction and high speed operation.

QIBR non-standard customized deep groove ball bearing

● Non-standard deep groove ball 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. Our QIBR enables non-standard deep groove ball bearings to operate safely and smoothly under radial load, axial load and combination load, by precise ball selecting and precision bearing raceway producing, to achieve optimum bearing performance.

● According to your request, QIBR are able to provide non-standard deep groove ball bearings, such as open bearings, closed bearings with dust cover, sealing ring or multiple rolling elements.

● For example the equal thin section deep groove ball bearings that are the width and height of bearings are with same size, deep groove ball bearings with full complement rolling elements and some inch sizes bearings.

Equal thin section deep groove ball bearing, B=（D-d）/2

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 balls are evenly distributed in the bearing rings and can be rotated properly.

The cage has stamped steel wave type, stamped steel rivet type, nylon or phenolic plastic.

QIBR offers a wide range of advice and options depending on the operating conditions.

Seals

In order to prevent contaminants from entering the inside of the bearing, QIBR uses a metal dust cover or a rubber seal with a metal skeleton.

QIBR are able to choose two types as a combination seals according to your working conditions, or choose different kinds of seal materials, such as nitrile rubber BUNA, acrylic rubber HYCAR, fluoro rubber VITON.

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 is precisely tailored to customer's temperature conditions, interference fit, misalignment of the bearing's 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 10%-20% longer than other bearings of the same model, through strict production process, high standard material selection, precision control.

The adopted steel balls

The steel balls in the deep groove ball bearings used by QIBR are mainly designed according to the load requirements of the bearing. The bearing ball sizes of different models are different, generally the value of rib coefficient Kd (ditch depth) range 0.35-0.40. , related to bearing diameter, such as 6000 series Kd = 0.35, 6400 series Kd = 0.40; 6200 and 6300 series, d ≤ 25mm take Kd = 0.35, d > 25mm take Kd = 0.40. Groove depth = Kd × steel ball diameter.

Classification and grade

According to the form of the seal structure, it can be divided into open bearings and closed bearings.

Closed bearings are classified into general dust cap seals, non-contact rubber seals and contact rubber seals. Usually, the sealed bearings are filled with grease lubricant. The amount of grease is 25% to 40% of the effective space of the bearing. If there are special requirements, we can make corresponding adjustments.

The bearing can also be processed installation groove on the outer ring to install the snap ring, according to the customer's installation needs.

Open type deep groove ball bearing

Deep groove ball bearing with outer ring can be installed with snap ring

Sealed deep groove ball bearing

Structure: Outer ring, inner ring, cage, grease / seal ring (introduction of product structure type)

Load: Mainly carry radial load and certain of axial load.

Type: Open bearing, dust cover seal (ZZ), contact seal (RS), non contact seal (RZ).

Features: The raceway is rounded, uniform distribution of steel balls, low friction, can be applied with high speed, high temperature and certain load

Bearing accuracy grade and division standard

The accuracy of rolling bearings is mainly divided into dimensional accuracy and rotational accuracy. The accuracy grade of the bearing has been standardized, and it is divided into five grades: level 6, level 6, level 5, level 4, and level 2. The accuracy is orderly increased from level 0, and it is sufficient for the general purpose of the bearing level 0, but if used for other conditions or occasions, it requires level 5 or higher precision to work with the equipment.

The following accuracy scales are based on the ISO standard and the ГОСТ standard, but their names are different.

Axial load: Load move along the axis.

Radial load: A load perpendicular to the axial direction.

Vibration level and application range of bearings (deep groove ball bearings, cylindrical roller bearings)

Bearing vibration (acceleration) is divided into five grades: Z, Z1, Z2, Z3, and Z4. Bearing vibration (speed) is divided into five grades: V, V1, V2, V3, and V4.

Z and V grade are applicable to the vibration test of deep groove ball bearings within the scope of the specified standard by the bearing manufacturer;

Z1 and V1 are suitable for finished products inspection of deep groove ball bearings and cylindrical roller bearings with general requirements for bearing vibration;
