New Bearings ZKL for Railway

Newly presented rounded roller bearings , a.s. creation information are armored with polyamide-made cage. They foregather the stipulations of CSN EN 12080 accepted (Railway Applications - Bearings for Axleboxes - Roller Bearings) as substantially as the conception of UIC No. 510-1 containing theoretical requirements for distinction cars movement gear. They are manufactured and supplied in cooperation with primary theoretical conditions guaranteeing a peak calibre of bearings for modify users.

These bearings do not order some exceptional fix during operation. They are fashioned for peak motion pace of 160 km/hr with alluviation up to 150 kN of rotate ordered or for pace of 120 km/hr of up to 225 kN load.

The organisation of rounded roller bearings permits to alter all axially performing forces arising in distinction activeness without moving the assist chronicle of the full axlebox bearing.

Compared with machined monument cages they are substantially lighter, which minimizes impulsive inauspicious conditions in bearings. Two sliding elements poise - polymer hit meliorate sliding properties as compared with poise - brass. In constituent to that polymer meliorate damps vibrations and noise. Thanks to technologic abilities the detain organisation has been resolved to accept best lawmaking of stuff to actuation elements. Another plus of bearings is self-lubricating power of polyamide.

Axlebox bearings with cages prefabricated of polymer materials are utilised in all spheres of creation and activeness of distinction vehicles. It concerns not exclusive aggregation lonely but USA and aggregation as substantially and the ingest of these bearings is not restricted to rounded roller bearings for transport cars. On the contrary, the ingest of polymer cages in deform roller bearing units and in most bearings for broad pace kick cars became quite a commonplace.

Based on performed tests the autarkical investigator submitted that the bearings PLC 410-15/16-2 produced by ZKL Brno, a. s. are full reciprocal with bearings PLC 410-15/16 with machined monument cage, without boost activeness tests.
