Deep Groove Ball Bearing 6300 series

Short Description:

Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball.

The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operation at very high speed or for large diameter bearings.

Deep Groove ball bearings with seals or shields are standardized. They contain proper amount of grease in advance.

BEARING MATERIALS

The performance and reliability of rolling bearings are greatly affected by the materials which the bearing components are made from.BXY bearing rings and balls are made of high quality of GCr15 vacuum-degassed bearing steel.Chemical composition of GCr15 bearing steel is basically equivalent to some representative bearing steel as the chart shown below:

BEARING INSTRUCTIONS

The bearings are coated with antirust agent and then packed and leave the factory.It can last for years if properly stored and well packed.Bearing storage should be noted as follows:

1. Keep in a place with a relative temperature below 60%;
2. Do not directly placed on the ground, at least 20 cm from the ground on the platform placed well;
3. Pay attention to the height when stacking, and the stacking height should not exceed 1 meter.
