The standard range of Lemcol rollers are manufactured with an ‘oval’ shaped formed axle. This effectively locks the axle in the frame and holds the inner bearing firmly thus ensuring maximum efficiency from the ball race. An internal spring at one end enables the axle to be laterally moved for ease of assembly, alterations to roller pitch or removal for maintenance.
Three ranges offered to suit standard applications and operating conditions.The rollers in curved sections are of the double differential type, enabling cartons etc. to maintain a controlled course and not wander to the outside of the curve.
Although manufactured to suit the Lemcol gravity conveyor frame, non-standard lengths and axle types are available on application.
If adverse operating conditions are encountered, it is important that you refer to your nearest Lemcol representative to ensure the best selection possible. For instance, galvabond rollers and polypropylene rollers with sealed stainless steel bearings and axles are available to suit moderate to heavy corrosive conditions.
As roller capacities quoted are for moving at objects, selection should also take into account possible impact, where a heavier roller is more suitable.
For ease of movement and reduction in damage, there should always be a minimum of three rollers under the commodity at all times. Where there are multiple sizes of products involved, roller pitch is determined by the smallest commodity to be moved.
Steel Rollers – 110kg Capacity
These rollers are made from 51mm O.D. ERW tube with 1.6mm wall, providing a strong and durable roller. The bearing is all steel construction incorporating a hardened steel, caged ball bearing, shielded and greased.
Steel Rollers – 60kg Capacity
These rollers are made from 51mm O.D. ERW tube with 1.6mm wall, offering an economical alternative to the 110kg steel roller. The bearing inner and outer is manufactured from acetal with a single row of carbon steel balls.
Polypropylene Rollers – 50kg Capacity
These rollers are made from 51mm O.D polypropylene tube with 4mm wall, UV stabilised but suitable for indoor use only. The bearing inner and outer is manufactured from acetal with a single row of carbon steel balls. These lightweight, quiet running rollers are used to reduce possible damage and are suitable where corrosive elements may effect efficiency or hygiene standards.They are not suitable for extreme corrosive conditions, where non-standard bearings and shaft material would be required.
