They comprise of solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions. Features and Benefits. Lower operating costs. Reduced maintenance due to improved lubrication. Lower heat generation. Less noise. Can support both axial and radial forces. Suffixes. C3 - Radial internal clearance larger than normal. TVH - Solid cage made from glass fibre reinforced polyamide 66. 2RS - Contact seals on both sides
