Type:Sendzimir Mill Bearings
Shoulder bearings have been projected on purpose for Sendzimir cold steel mills: they can be used also in straightening or flattening machines. Shoulder bearings show different shapes in construction, in order to fulfill several application requirements. Cylindrical roller shoulder bearings can have up to 4 rows of rollers, with cages or without cages. They have the advantage of having a simple shape and a high radial load capacity. Some series are manufactured with entire edges obtained on the outer ring, other series are without entire parts, with distance rings and lateral thrust rings. The material used for the production of the outer ring can be of two types, according to the requests of the customer
- 100CrMo7.3 with core hardening,
- 18NiCrMo5 with 3,5 mm cementation depth,with extreme precision in the working tolerances, radial clearance, hardness and load capacity.
Sendzimir mills are known worldwide for their ability to roll extremely hard materials to very thin gauges with few, if any, intermediate anneals. They consistently maintain quality aspects that are difficult, if not impossible, to duplicate on other mills.
sendzimir mill rolling bearings (also called backing up roller bearing) were designed to improve the precision of steel rolling products. The outside of these bearings straightly touch to intermediate roll.And they can carry rolling component. The outer ring have good wear resistance, inner have enough long rolling fatigue life. Outer ring can be regrinded. And the bearing will still rotate as usual after regrinding. The bearing have high impact resistant because of soft inner part. Deep enough surface hardened. Except high rigid, can increase frequent of outer diameter repair. sendzimir mill rolling bearings have high fatigue resistant because of good material.
