Conveyor Rollers

Ashland Conveyor Products manufactures gravity rollers and sprocketed rollers. The following information is intended to guide you through the proper application and selection of conveyor rollers. For specific conveyor rollers not listed contact a sales representative at Ashland Conveyor Products.

Conveyor Roller BF or Between Frame
The length of gravity conveyor rollers is normally described in terms of BF, the dimension between the frame or between the rails of the conveyor.

Conveyor Roller Diameter and Gauge
The conveyor roller tube diameter and gauge are required when specifying a roller. The diameter is the outside diameter of the tubing and the gauge is the wall thickness of the tubing. The following conveyor roller diameters and gages are Ashland Conveyor Products standards. Also shown are tube materials and shaft size.

Bearings
Standard conveyor roller construction utilizes “commercial grade” (also known as “non precision”) bearings. Semi-precision and precision bearings are also available. Standard bearing lubrication is light oil; however, grease packed is also available. Generally light oil lubrication is used for gravity applications as it rotates more easily. Grease packed is normally used for power conveyor applications or harsh environments.

Conveyor Roller Capacity
Conveyor roller capacities are calculated to CEMA standards. The capacity is limited to the bearing capacity, shaft deflection, tube deflection, or tube strength. Refer to specific roller tables for conveyor roller capacities.

Axle Construction
Spring retained axle rollers are Ashland Conveyor Products standard construction. These conveyor rollers contain a spring that is captured between one of the bearings and a dimple on the shaft. When pushed on one end the shaft will slide through the roller allowing for insertion into the frame.

Pin retained rollers contain no spring or dimples to retain the shaft. Instead, the shaft is drilled on each end for a retaining pin. Once a roller is placed in a frame the retaining pins are inserted. Pin retained rollers must be specified at the time of quoting or ordering.

Sprocketed Conveyor Rollers
Sprocketed rollers are used for chain driven live roller conveyors. A typical arrangement is illustrated below. Standard construction includes grease packed and sealed bearings. Can be supplied as spring or pin retained. Length measurement should be from bearing hub to bearing hub.
