Product Description

• Double-acting thrust tapered roller bearing construction.
• Used extensively on work roll axial positions in metals rolling mill
applications where axial loads are very high.
• Design variants include one tapered inner race and two flat outer
races, or one flat inner race and two tapered outer races.

Four row cylindrical roller bearings Rolling ring wall with small friction fit High-speed rotation. According to ring without ribs, it can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing inner ring, outer ring separable structure. No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free end bearings. In an inner and outer side of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy machined cage. But there are also part of the use of polyamide forming cage.
