COOPER02-BCP-207-EXComplete Split Cylindrical Roller Bearing Pillow Block Unit, 2-7/16 in Bore, Heavy-Duty 02 Series, Expansion Type

Product Description

What this part is

A complete Cooper split cylindrical roller bearing pillow block unit for a 2-7/16 in shaft, heavy-duty 02 series, expansion type. Every component — inner race, outer race, cage and roller assembly, cartridge and housing — is split into halves, so the whole unit assembles around the shaft rather than sliding on over the end of it.

Correcting the source data — this is a pillow block, not a flange:
The previous listing described this as a flange mount bearing. It is not. In Cooper’s own nomenclature the configuration letters read as B + C + P: Bearing, Cartridge, Pedestal, which Cooper defines as a “complete pillow block.” A Cooper flange unit carries a different code entirely — BCF for a round flange or BCDF for a square flange. There is no flange anywhere in this part number.

This is a high-consequence correction. A buyer needing a flange unit to bolt to a vertical face would receive a pedestal that bolts to a horizontal base — an automatic return on a $1,799 assembly. The previous description also stated a 3 in bore in one place; the bore is 2-7/16 in, as the 207 in the part number encodes.

Decoding the order code

02 — series: heavy duty. Not a size and not a material codeB — Bearing (the split cage, roller, inner race and outer race assembly)C — Cartridge (the split cartridge halves and seals)P — Pedestal (the split housing base and cap). A P-only code, such as P 04, would be the pedestal on its own207 — bore, with the last two digits in sixteenths of an inch: 2-7/16 inEX — Expansion type. The outer roller track is plain, so the bearing carries radial load only; the inner race is clamped to the shaft and the roller set is free to move axially along the outer track. The fixed alternative is GR, which carries radial and axial load

What is in the box

The complete assembly, in three sub-assemblies: bearing 02 B 207 EX, cartridge 02 C 207 EX, and pedestal P 04. That matters because Cooper sells all three separately, and “02-BCP” is the code that means you get all of them. If you were quoted a cheaper 02-B-207-EX elsewhere, that is the bearing only, with no cartridge and no housing.

Why split bearings exist — the whole commercial case:
A split bearing costs several times what an equivalent solid bearing costs, and the entire justification is downtime. Fitting a solid bearing to a mid-shaft position means either sliding it the length of the shaft past every obstruction, or uncoupling and lifting the shaft out. On a long conveyor drive, a fan shaft, a crusher or a marine propeller shaft, that can mean days of work and the removal of adjacent gearboxes, couplings and sheaves.

A Cooper split unit assembles around the shaft in situ. You unbolt the cap, drop the halves in, bolt it back up. Replacement time falls from days to hours, and no adjacent equipment moves. If you are costing this part against a solid pillow block on purchase price alone, you are measuring the wrong thing — the comparison is against the labour and lost production of the shaft removal you avoid.

Why expansion and not fixed — read this before you buy:
The EX suffix is not a minor variant. An expansion bearing deliberately allows the shaft to grow and shrink axially through the bearing, and it carries no axial load at all.

On any shaft long enough to matter, thermal growth is real: a steel shaft grows roughly 0.0000065 in per inch per °F, so a 20 ft shaft rising 60 °F grows about 0.09 in. If both bearings on that shaft are fixed, that growth has nowhere to go and the bearings fight each other until one fails. The standard practice is one fixed (GR) bearing to locate the shaft axially, and every other bearing on the shaft expansion (EX). Do not use this unit as the locating bearing, and do not fit two fixed bearings on one shaft.

Published data, and what is missing

Bore: 2-7/16 inSeries: 02, heavy dutyHousing style: split pillow block / pedestal, 2-bolt base (Cooper’s separate BC4P code covers 4-bolt bases on 02-series sizes 211 to 400, so 207 is 2-bolt)Configuration: expansion, radial load onlyPedestal: P 04Bearing type: split cylindrical rollerWeight: approximately 16.9 kg / 37.3 lb (distributor figure, not an SKF-hosted one)

Radial and axial load ratings, base-to-centre height, bolt centres and overall dimensions are not published in any accessible online source — Cooper places them in the printed product catalogue’s load-capacity and inch-size dimension sections. They are deliberately omitted here rather than estimated. On a part at this price, ask before you order and the figures can be pulled from the printed catalogue.

Seals are not specified by this code. Cooper’s standard is an ATL aluminium triple-labyrinth seal up to 12 in bore; some listings of this part carry an additional AT or ATL suffix, so confirm the seal execution if your environment demands a specific one.
