Bearings with a bore size from 2 mm to 9 mm. Available straight or flanged in open or shielded configurations. Available on both Chrome Steel or Stainless Steel. They enable manufacturers to further downsize their products without compromising quality and performance.
Extra Thin Series
Bearings with a bore size from 10 mm to 95 mm. Extra-thin type flanged bearings are used for the downsizing and lightweight designing because of their thin cross section.
Large Size Ball Bearings
Mass-producible large-sized stainless steel bearings have achieved greater durability and high precision. Resistant to rust and corrosion, this type of bearing with high versatility can be incorporated into any product.
Inch Extended Inner Ring
The bearings have similar characteristics to a radial ball bearing with the exception of the extended inner ring. This can help with mounting by removing the need for spacers or washers.
Ball Thrust Bearings
Consist of two precision chrome steel washer or rings and a ball complement that is spaced by a bronze retainer. Primarily see these types of bearings used in applications with axial loads only.
