ARVIS have been making Steel SN Plummer Blocks since 1981. As a result of their vast experience gained in this field and due to demand from the trade, we are now able to offer the whole range of sizes from SSNT509 to SSNT532 (40mm to 160mm) either from stock, or very short delivery, together with the 200, 300 and 600 series blocks These are manufactured to a system approved by BSI to ISO 9002, where the use of State-of-the Art CNC machines and three Axis CMM for inspection enables very high quality standards to be maintained.
SSNT Plummer Blocks are machined from steel castings and should be used to replace broken popular cast iron SN, SNE, SNV, SNA, SNH etc, which may have failed due to over-loading, excess vibration, impact damage, mis-use, or simply in situations where the popular standard plummer blocks are just not man enough for the job.
Typical applications would be in heavy industry such as Steel-making and Processing, Quarries and Mining, Cement Works and Pre-cast Concrete Machinery, Brick & Tile Industry, Heavy Duty Conveyors, Paper Industry, Lifts and Cranes, Furnaces and Foundry Plant, Abattoirs, Various Large Processing Plant, etc.
These indestructible, very heavy duty Steel Plummer Blocks are to internationally accepted ISO standards. They have solid bases which can be drilled for two or four-bolt fixing, and are designed to accept standard self-aligning ball bearings or spherical roller bearings. The bearings may be mounted directly onto a machined shaft or used with adapter sleeves.
Criptic-Arvis holds stocks of part-finished SSNT Plummer Blocks. In the event of an order these are then ‘customised’ and finished off to specification. Boundary dimensions or end bore diameters can be varied, ends of base machined square for location or special lubrication facilities provided.
Various seal options are available according to the customer’s environmental needs, the most popular being felt or lip seals, but labyrinth seals or vee ring seals are a useful alternative. Closed end covers are available as required and grease nipples are provided as standard.
All steel housings designed and manufactured by Arvis are guaranteed against breakage and will be replaced free of charge should the housing fail before the insert. You will also receive a free replacement rolling element with your new housing. (Conditional on cap bolt loading where applicable. See individual housings.)
