Product Details

Description

Double row tapered roller bearings can withstand radial loads while receiving biaxial axial loads. The clearance has been adjusted before the product leaves the factory, so it can be installed directly without adjusting the clearance. Double row tapered roller bearings limit the axial displacement of the bearing in both directions relative to the housing within the axial clearance of the bearing. The TDI type is an inward-oriented double-row tapered roller bearing with similar performance to the face-to-face installation of two single-row tapered roller bearings. It has a smaller installation space than the outward-oriented double-row tapered roller bearing (TDO type). However, the rigidity is slightly poor, and it is often used as a positioning end bearing that is subjected to medium load, such as a roller bearing positioning end, a speed reducer, and the like.

Configuration

Paired Back-to-back Tapered Roller Bearing D The 40-170Mm configuration consists of a double row tapered roller bearing consisting of two single cones, one double cup, two pressed steel cages, two rows of back-to-back rollers and one cone Spacer (flat or with annular groove and lubrication hole). The width of the tapered spacer allows the correct BEP. The TDO bearing with blind holes in the double cup is particularly suitable for mounting in the housing in a loose fit, since the hole counter drilling allows the pin to be inserted to avoid double cups and Sliding between the housings.
