The Mulco tension roller Type M comes in seven standard sizes. An important feature of these tension rollers is their rigid, vibration-resistant load bearing design. They also feature a generously dimensioned D1 base diameter, which absorbs the forces acting on the belt pull.
The tension rollers are over-mounted on the machine wall and the ball race and the load bearing structure are made of AlCuMgPb (F38). It is easy to adjust the belt pre-tension force because of the eccentrical fitting. To ensure the swivel motion around the mounting axle, the face spanner can be used.
High quality grooved ball bearings are fitted to the Mulco tension rollers. The first filling of the bearings consists of a high-performance lithium saponified grease to ensure life time service. The greases are short-time temperature resistant up to 120°C. Permanent temperatures of 70°C and above will lead to a reduced useful life of the grease.
