Lightweight KB025AR0 open single-row angular contact bearing

KB025AR0 is a 30°contact angle constant slim section bearing with dimensions of 63.5*79.375*7.938mm and an open design. Made of high-carbon chromium bearing steel and fitted with a brass cage, it offers stable precision and can withstand radial and unidirectional axial loads, making it suitable for precision instruments, automation, and medical equipment.

Thin Section Bearings are mainly lubricated with grease, and the grease is added at the factory according to a fixed ratio.The grease base components and thickener ratios are uniform, making it suitable for the internal operating space of the bearing.The amount of grease filler should be 30% to 50% of the bearing's internal cavity volume. This ratio balances lubrication effect and rotational resistance.The grease adheres evenly to the contact area of the rolling elements and raceways, continuously forming an oil film.The sealed structure reduces grease loss, eliminating the need for frequent grease replenishment under normal operating conditions.For special operating conditions, the grease formula and filling ratio can be adjusted. For special operating conditions, the grease formula and filling ratio can be adjusted. For high-speed and high-temperature models, a suitable special grease will be selected.

Due to their stable precision and structure,thin Section Bearings are widely used in industrial and civil sectors.In the field of electromechanical power, it is widely used in the spindles and power transmission components of various small and medium-sized motors; in the field of automation, it is applied to assembly line transmission units, precision motion modules, and moving joints of intelligent equipment.In the fields of civil and general machinery, it is compatible with ventilation equipment, water supply pumps, and transmission structures of household appliances.Different precision levels can be selected as needed, with strong overall compatibility. The protective structure can cope with normal field environments and meet the requirements for long-term continuous operation of the equipment.

Thin Section Bearings provide a uniform load distribution during dynamic operation, making them suitable for medium- and high-speed, medium- and small-scale alternating load conditions.P4 and P5 levels correspond to different rotational runout limits, and the vibration amplitude is controllable during high-speed operation.The rolling elements and raceways maintain stable contact, resulting in low frictional loss and a gradual temperature rise during continuous operation.The internal lubricating film can be maintained intact under dynamic pressure, effectively preventing dry friction.There are no obvious shocks or abnormal noises during start-up, shutdown, and speed change. The dynamic response is stable and it can maintain operating accuracy for a long time, making it suitable for various transmission mechanisms for continuous operation.
