Conveyor Roller Bearings
Rolcon uses a variety of different conveyor roller bearings depending on the application in the conveyor system. Generally 4 different styles are offered:
Precision bearings are standard in Rolcon conveyor rollers. These bearings are suitable for any conveyor system speed, but are typically used when speeds exceed 400 rpm or when conveying heavy material handling loads across the conveyor system. These bearings have hardened and ground balls, raceways and retainers. They are available shielded or sealed. These are ABEC-1 bearings and come either grease packed or oiled.
Semi-Precision bearings are typically used for higher speed conveyor system applications up to about 400 rpm. These bearings have hardened raceways and hardened steel balls with a retainer to separate the balls. Generally give longer life and are quieter than non-precision.
Non-precision bearings are typically used for slow to moderate speed conveyor system applications. These bearings have stamped outer races, carbon steel balls and ground raceways. As a rule of thumb, they do not last as long and are noisier than precision and semi-precision bearings.
Commercial Grade Stainless Steel
These bearings are used for conveyor rollers that are going into a conveyor system in corrosive material handling environments. Machined raceways and series 300 stainless steel balls are good for light to moderate loads and can be used for high speed conveyor systems.
Roller Axle Construction
All Rolcon conveyor rollers are double spring retained. This is achieved by making two nicks on the roller axle and installing a spring between the nick and the roller bearing. This allows for ease of installation in the conveyor system since both sides of the axle are free to move.
Pin or Ring Retained Axle
This axle has a hole drilled in each end to accept cotter pins or hog rings. Pin retained axles are offered on all sizes of Rolcon conveyor rollers.
Conveyor Roller Construction
This is the standard way in which a Rolcon conveyor roller is assembled. The roller tube is crimped down over the roller bearing to hold it in place. The bearings are not replaceable when made in this manner.
On some of the heavier gauged tubing, the roller tube needs to be bored to accept the roller bearing. The bearing is then held in place by a press fit.
This conveyor roller utilizes a roller bearing that is pressed into an adapter. The adapter is then press fit into the roller tube. In some cases the adapter will be crimped.
Conveyor Rollers With Sprockets
Rolcon utilizes standard type A sprockets for our Chain Driven Conveyor Rollers. Other sprockets are available upon request. The sprockets are welded to the conveyor roller for use in Chain Driven Live Roller Conveyor Systems. Single and multiple sprockets are available. Location of sprockets, chain size and number of teeth must be specified. Sprockets may also be purchased individually.
Conveyor Rollers With Grooves
Rollers can be grooved to accommodate drive belts and rollers used for handling materials on line shaft conveyors. The location of the groove must be specified. Standard roller diameters are 1 3/8, 1 5/8 and 1.9.
