629 2RS Miniature Deep Groove Ball Bearing for Agricultural Equipment | 9×26×8 mm
The 629-2RS is a General-Purpose Deep Groove Ball Bearing engineered for applications requiring enhanced sealing against contaminants and moisture. Featuring double rubber contact seals (2RS) on both sides, this metric bearing provides superior protection against dust, dirt, and light fluid ingress. With a 9mm bore, it is a versatile and reliable choice for electric motors, appliances, agricultural equipment, and machinery operating in potentially dirty or damp environments.
629-2RS Deep Groove Ball Bearing 9x26x8 mm | Standard Series | Double Rubber Sealed
A robust and widely used bearing built with the universal deep groove geometry. Designed for dependable performance at speeds up to 25,000 r/min (Oil). The 629-2RS is capable of supporting moderate radial loads and is particularly valued for its effective sealing, which extends bearing life in less-than-ideal conditions.

Ideally suited for applications where environmental sealing is a priority:
The dual low-friction synthetic rubber seals (2RS) provide effective two-sided sealing against common contaminants such as fine dust, dirt, and moisture splash. While these contact seals introduce slightly more rotational resistance than non-contact shields, they deliver superior defense for the internal lubricant in challenging operating conditions.
As part of the standard series with enhanced sealing, the 629-2RS offers a robust balance between load capacity and environmental protection. Its design is particularly well-suited for applications where preventing contamination inside the bearing is essential for longevity.
Manufactured to established industrial tolerances and available in higher precision grades (up to P5), this bearing is engineered to minimize friction even with contact seals. The result is quiet, smooth, and dependable operation in a variety of light machinery, fans, and motor applications.
