About: CMI - RP 104 Pulley
Available with needle bearings or sealed ball bearings.
Needle Bearings:
These are the original CMI rescue pulleys that set the standard for lightweight, compact, yet functional rescue pulleys 50 years ago. Now featuring stainless steel axles on all models, they are built around either glass-filled Celcon or aluminum sheaves and employ either a sintered bronze bushing or sealed needle bearing. All models accept up to 5/8-inch diameter ropes and feature our now famous "wide skirt" sideplate design for maximum rope protection. These are the most versatile rescue pulleys available and their lightweight, compact design makes them a pleasure to carry.
High strength in a compact design. Stainless steel sideplates, 2 3/8-inch aluminum sheave, needle bearing, and stainless steel axle.
Ball Bearings:
We have taken some of our ever popular designs and added sealed ball bearings instead of sealed needle bearings. Needle bearings are a good choice for slow, controlled pulls while ball bearings allow for greater speeds to be utilized without the risk of damaging the bearing. All new ball bearing pulleys come laser marked with "ball bearing" so they are easily distinguished from other pulleys.
