Cam rollers SKF 305806 C-2RS1

Cam rollers SKF double-row, seals on both sides, profile radius of the convex rolling surface R = 400 mm. Double row ball bearings - support rollers are designed on the basis of double row angular contact ball bearings and have a contact angle of 25 °. They are lubricated units ready for installation, which are used in all types of cam drives, conveyor systems, etc. These products are equipped with stamped steel shields to hold grease inside the bearing, as well as protect the bearing from external contaminants. They can be supplied in two versions: with a convex rolling surface of the outer ring, series 3058 (00) C-2Z and with a cylindrical rolling surface of the outer ring, series 3057 (00) C-2Z. Bearings - support rollers with a convex rolling surface of the outer ring should be used in the case of an angular skew relative to the guide surface in order to reduce edge stresses. Double row ball bearings - support rollers are equipped with two 6.6 polyamide cages, centered on balls and designed for operation at temperatures up to +120 ° C. Under normal operating conditions, bearings - support rollers do not need maintenance. However, when operating in conditions of high humidity and penetration of solid pollutants or during continuous operation at temperatures above 70 ° C, they require re-lubrication. A lubrication hole is provided in the inner ring for this purpose. For lubrication, lithium-based grease must be used, preferably SKF LGMT 3. To avoid damage to the protective washers, grease must flow slowly, LR5206-2HRS-TVH-XL, LR 5206 2HRS TVH XL, LR52062HRSTVHXL, LR5206-2Z-TVH-XL, LR 5206 2Z TVH XL, LR52062ZTVHXL, LB3206B2ZRSTNG, LB3206B2RSRSTNG, 306806C-2Z, 306806 C-2Z, 306806 C 2Z, 306806C2Z, 305806 C-2RS1, 305806 C 2RS1, 305806C2RS1, LR 5206 KDDU, LR5206KDDU,
