ball bearing / single-row / rubber / maintenance-free

?? "JSC HARP" is one of the main suppliers of bearing products to the conveyor of JSC ZAZ.?.

Among the latest developments there is an upgrading of the front wheel hub bearing 6-256907???12L19 for automobiles LANOS, SENS, Tavria, Slavuta, VAZ-2108, VAZ-2109, VAZ-21099, VAZ-2110, VAZ-2111, VAZ-2112 which is serially-supplied to the conveyor of the automobile plant since 2011. Also the upgraded hub bearing is successfully used in the manufacture of agricultural implements - disc harrows, cultivators - in maintenance-free bearing unit HARP-AGRO

Designation of the modernized bearing is 6-256907???12L19.

This bearing has significantly improved characteristics on durability and efficiency comparing with 6-256907??1?1?17 earlier serially-produced and delivered to the conveyor of JSC ZAZ.

Improved characteristics on durability and efficiency of the upgraded bearing 6-256907???12L19 are achieved by means of:
? production of bearing rings from work billets obtained by hot forging;
? usage of lip type seals instead of ordinary rubber seals;
? usage of lubricant CHEVRON SRI GREASE NLG12, usage of lubricant BERUTOX 18EP FE (L20) is allowed instead of Litol-24.
Implementation of these improvements increases durability of the bearing in two or more times, increases tightness of the bearing, secures the bearing against moisture and dirt. The cage design provides a good distribution of lubricant between working surfaces of the bearing parts
