FC bearing housings.
Extra heavy duty and interchangeable for SN style blocks.
GUARANTEED
UNBREAKABLE*
(Conditional on Cap bolt Loads for Split
series FC-S)
The series FC Plummer Blocks are designed for applications where extra strength and resistance to shock loads are required, they will withstand high stresses in all planes.
The housings conform with
BS5646: Part 4: 1979 and are dimensionally interchangeable with SN, SNA, SNL,
SNH plummer blocks
manufactured with this or the superceded standard ISO R/113.
Housings and end covers are manufactured from hot rolled steel plate to BSEN10025 S275, having a minimum yield strength of 220N/mm˛
(14.25 tons/inch˛ and a corresponding elongation factor
20-22%.
Housings are produced in two basic designs - solid housings and split. The top cap of the
split housings is precisely located by two dowels and retained by two high tensile socket
cap screws; housing top caps and bases are not interchangeable.
Both types of housings can accommodate a range of double-row ball and spherical roller
bearings; these bearings may have a parallel bore (metric shaft sizes only) or incorporate
an adaptor sleeve (metric and inch shaft sizes).
The housing bores are machined to tolerances that produce a loose fit with the bearing
outer race; this ensures that dimensional inaccuracies, slight misalignment errors in
mounting and thermal expansion of the shafts are accommodated in the housing itself.
Axial location of the bearing within the housing is achieved by use of bearing locating
rings. In all cases the bearing should be located centrally within the housings.
Series FC housings are designed primarily for grease lubrication, and unless otherwise
specified are provided with felt seals; these are normally employed for peripheral speeds
up to 4 metres/sec. And temperatures up to 100 Deg C. Before using felt strips they should
be soaked in hot oil for a few minutes. A grease nipple is provided for periodic
relubrication; a pressure relief valve to guard against overfilling can be fitted on
request.
For applications where the standard range of steel housings are not suitable
e.g.- oil/ oil mist lubrication. Alternative mounting holes, etc. we can offer specially
designed housings to meet most specifications - please ask for details.
When ordering please state the bearing you intend to use and type of end covers required for seals.
Bearings can be supplied with housings if required.
