Steel Roller

Steel rollers are fitted with greased bearings. They may be used in applications up to 100°C. It is important that the roller is always wider than the belt that you are trying to tension. To work out the size you need to look at the description below. The first number is the outside diameter of the roller, and the second number is the roller width. For example, SR-30-M8, has an outside diameter of 30mm, and is 35mm wide. It uses an 8mm bolt passing through it.
