BEARING (6203RS) - JDNA Parts Store - bearing 6203rs
Now an established brand within the SKF Group, Cooper Roller Bearings product ranges will henceforth be marketed as ‘SKF Cooper split bearings’.
The cartridges have a spherical outer surface that fits into a conforming surface in the mounting unit rather like a ball and socket joint; any shaft misalignment tends to move the cartridge, seal and bearing together, maintaining the seal on an axis parallel to the shaft. This configuration allows extremely close tolerances to be maintained between the housing and the shaft, delivering a sealing performance that is recognised as one of the best in the anti-friction bearing industry.
Aluminum Nipple
Aluminum pipe fittings are used only in specialty applications where their uses and limitations are understood. They are not designed for use in general shop water or air plumbing layouts (refer to traditional metals like brass, steel/malleable iron, stainless steel, plastics, etc. for general plumbing applications). Aluminum to aluminum pipe threads are not designed to be removed or re-tightened as they will bind very quickly and easily (ie. the friction of threading together will cause the aluminum to bond to itself - PTFE sealants, pastes, or tapes can lessen the effect but will not prevent it). Therefore, once aluminum to aluminum threads are threaded together, it is considered permanent and leak paths would be difficult to eliminate (butt weld aluminum fittings are available, N205WD, N210WD, N225WD, etc). As a general guide, they can be used for vacuum or maximum 150 psi at ambient temperatures, but they can be welded and tested for other pressure ratings in certain applications. If using aluminum in combination with other metals, users must understand electrolysis and galvanic corrosion (especially with copper or steel with aluminum) as water, salt water, and other elements will degrade the metals. When attaching caps or plugs to aluminum tanks, it is better practice to use stainless steel caps or plugs (or plastic/nylon/poly) so they can be removed. Most "Cast Aluminum" pipe fittings are made of A356.2 alloy, and "Couplings, Nipples, and Sch 40 Butt Weld fittings" are made of 6061-T6 alloy. Threads conform to ASME B1.20.1.
Gothenburg, Sweden, 15 January 2018: SKF acquired Cooper Roller Bearings Co Ltd in 2013 as part of the US based Kaydon Corporation, Cooper’s parent company at the time. Following a period of consolidation within the SKF, it has now been decided that all Cooper Split Bearings ranges will be marketed under the name of SKF Cooper going forward.

As well as their complementary product ranges and reputations for engineering excellence, Cooper and SKF have one other thing in common: both mark 1907 as a particularly momentous year in their respective histories. 1907 was the year that Cooper’s founder, Thomas Cooper patented the world’s first split rolling element bearing, and in that same year Sven Wingquist invented the first self-aligning bearings and founded the Svenska Kullagerfabriken company – nowadays more commonly known as SKF.
SKF Cooper split roller bearings can be fitted, removed and inspected without having to dismantle surrounding equipment, providing savings in terms of reduced maintenance and downtime. The products include both split cylindrical roller bearings and split double row tapered roller bearings, the latter with the ability to take axial loads in either direction. Both are housed and sealed in special swivel cartridges, which are suitable for mounting in pedestal or flanged outer housings.
SKF Cooper products will continue to complement the growing SKF portfolio of complete solutions for the marine, mining, quarrying, construction and energy sectors. In addition to the brand name change, the channels to market for SKF Cooper products, including responses to customer enquiries, product supply and after-sales support, will be handled on a global basis through local SKF sales outlets going forward.
