What features do the rollers need to have?As most rollers are exposed to dust and water contamination, and the material is worn or corroded by the roll body, the ideal rollers for our products are developed with bearing seal configurations that can be adapted to the different environments in which they are used, so that users can choose the product that is more suitable for their use.The three main series of GCS rollers for saleModel: GCS-NS 6204 SeriesModel: GCS-LS 6204-6205 SeriesModel: GCS-RS 62-63 seriesMain features (energy saving products)1. Robust design structure for heavy duty applications.2、 The welding of the steel tube and bearing seat of the rollers is done by a precision concentric automatic welding machine.3、 The cutting and processing of the steel tube and shaft is done by CNC automatic equipment.4、 In order to achieve a good fit between the shaft and the bearing, the shaft end is precision roll-ground.5、 The assembly of the rollers is done by automatic equipment and the rotational performance is 100% tested.6、The rollers and support parts can be manufactured according to DIN/AFNOR/FEM/ASTM/CEMA standards.7. The outer guard is made of high strength alloy.8. Continuous lubrication and maintenance-free.9. Minimum 30,000 hours working life, longer depending on the load.10, Complete vacuum seal: internal seal, 3 groove labyrinth seal, external V-shaped rubber ring and centrifugal self-cleaning chamber. (Tested by the usual experiments against: water, salt water, powder, sand, gravel and dust)Raw materials and specificationsShaft: Cold drawn steel ST37 DIN17100, E24 AFNOR NFA 35501.Rods: 20.2 25.2 30.2 40.2 ISO hll precision Ground to 20,25,30,40 precision in the same bearing and seal assembly areaGround to ISO h6.Steel tubes: welded to DIN 2394, material ST37 to DIN 17100.Bearing seats: cold stamped to ISO M7 accuracy, raw material deep stamped steel to DIN 1623-1624.Inner sealing ring: lip edge seal material NYLON6 (ISO Pa6).Bearings: Deep groove ball bearings (clearance class C3) DIN 62 63 series.Labyrinth seal: 3 groove type, material NYLON6 (ISO Pa6).Cover: Raw material deep-drawn steel to DIN 1623-1624Outer sealing ring: Sliding V-shaped rubber ring in wear-resistant, low-friction, oxidation-resistant nitroso-rubber.Protective cover function: used mechanically to protect the life of the rollers from axial oscillation and vibration; made of corrosion-resistant zinc-magnesiumaluminium-copper alloy.Lubricating grease: to ensure that the roller bearings are continuously lubricated for a long time, use grade 2 and 3 long-lasting lithium-based grease.We are confident that you will find the ideal choice for your business or organisation.
