Single roller bearing sheave for mounting in an OPF block.
To be used for example in a main sheet system where the high loads cause excessive friction on the blocks, and makes movement of the car difficult.
That can be solved with these roller bearing sheaves that offer a very low friction and great smoothness.
ATTENTION! Be aware of the loads! See scheme below.
The self-captive delrin double side ball bearing reduces friction on the sides.
The sheave is easy to clean and maintain; Just rinse with clean water.
| Size sheave (D) | Ø70mm | Ø80mm |
Ø100mm |
| D | 70 mm | 80 mm | 100 mm |
| d | 12 mm | 16 mm | 20 mm |
| T | 16 mm | 19 mm | 21 mm |
| Ø line Max. Ø | 12 mm | 14 mm | 16 mm |
| Weight | 95 g | 160 g | 265 g |
| Free Rolling Load* | 1000 kg | 1600 kg | 2400 kg |
| Maximum Load** | 1200 kg | 2000 kg | 3200 kg |
*FRL: For good sliding and low friction this value must not be exceeded.
** ML: Load higher than Maximum Load will cause permanent deformation and damage of the bearing.
