Rope pulleys with plain bearings

BIS 3017

Rope pulleys with plain bearings have many application-oriented advantages. Because of its easy construction, rope pulleys with plain bearings are more cost efficient than those with roller bearings. The maintenance intensity is reduced to a minimum. Rope pulleys with plain bearings can be used under extremely hard environmental conditions.For example they are often used in hydraulic steelworks.

Rope pulleys with deep groove ball bearings

BIS 3018

Rope pulleys with deep groove ball bearings according to BIS 3018 are equipped with two bearings but no inner bushing. Using a special constructed shaft, the bearings are held on position. Because of the slim ball bearings, the total width of the rope pulley assembly can be constructed very small. That leads to optimal installation dimensions.

Special constructions can be done according to your requirements.

Rope pulleys with deep groove ball bearings and inner bushing

BIS 3021

Rope pulleys with deep groove ball bearings and inner bushing according to BIS 3021 are equiped with an inner bushing. The bushing serves to position and fix the bearings and to seal the lubrication. Normally the bushings are designed with sidewards subsections to enable an anti-twist protection. This depends on the constructive design of the bottom block. In accordance with your application, we can design the suitable solution.

Rope pulleys with cylindrical roller bearings and inner bushing

BIS 3022

Rope pulleys with cylindrical roller bearings and inner bushing according to 3022 are characterised by their high load ratings. The load capacity of cylindrical roller bearings is significanly higher than those of deep groove roller bearings. The broad construction of the cylindrical roller bearings finally leads to broad installation dimensions which have to be considered in the constructive design of the bottom blocks. In any case it is possible to adjust the construction to your requirements.
