B71922-E-2RSD-T-P4S-UL

The B71922-E-2RSD-T-P4S-UL is a super-precision angular contact ball bearing engineered for exceptional performance in high-speed, high-precision applications. This bearing features a 20° contact angle (E) and is constructed with ceramic balls, which provides a significant advantage in achieving higher speeds and greater rigidity compared to traditional steel ball bearings. It comes equipped with non-contact seals (2RSD) on both sides, offering excellent protection against contaminants without increasing rotational friction, making it ideal for cleanroom environments or operations where maintaining low torque is critical. The design is universally ground (UL) for easy and versatile mounting as single units or in pairs, providing flexibility for various machine tool spindles, robotics, and measuring equipment.

The key benefit of the B71922-E-2RSD-T-P4S-UL lies in its combination of extreme accuracy and operational longevity under challenging conditions. The P4S tolerance class signifies a very high level of dimensional and running accuracy, ensuring superior rotational precision and consistency. Its T-type cage, made from a hard-wearing, lightweight phenolic resin, is guided by the balls, which contributes to its excellent high-speed capability and low heat generation. This robust construction, paired with advanced material science, results in a bearing that delivers enhanced machine performance, longer service intervals, and reliable operation where precision cannot be compromised.
