Bearing Housings
This group covers everything you bolt a separately-selected bearing into: split plummer blocks, inch split pillow blocks, non-split and take-up housings, flanged and two-bearing housings, conveyor pulley housings and mill trunnion housings. Work down from the duty to the family, then pick the bearing, seal and locking element together. SES holds the range as an authorised SKF distributor, covering families SNL, SNLN, SONL, SAF, SAW, SDAF, SBD, THD, FNL, PD, SDVD, FSDR; shaft span From around 20 mm to well over a metre on mill housings; materials Grey cast iron, ductile iron, cast steel; bearing types Spherical roller, CARB, self-aligning ball. Executions include split plummer block housings (SNL, SNLN, SONL), split pillow blocks, inch (SAF, SAW, SDAF), non-split pillow and take-up housings (SBD, THD), flanged housings (FNL), among others. It is specified most often into belt conveyor drive, head, tail and bend pulleys and fan and blower shafts in power plant. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Bearing Housings in the parts of a plant where this particular duty actually occurs. In practice that means belt conveyor drive, head, tail and bend pulleys, fan and blower shafts in power plant, crusher, screen and mill drive shafts, and equally bucket elevator and drag chain shafts, paper machine and calender roll ends, grinding mill trunnions in cement and mineral plant. What links them is the duty rather than the machine name — construction: Split cap and base, or one-piece. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Bearing has to be inspected or changed without pulling the shaft — A split housing — SNL, SAF or SDAF. A non-split housing means the shaft comes out, and on a long conveyor that decides the shutdown length, not the bearing. Drawings and shafting are in inch sizes — The SAF, SAW or SDAF families. Fitting a metric SNL over inch shafting with a spacer is a lash-up that never seals properly. Radial load is high and the support is a fabricated frame — Cast steel or ductile iron. Grey iron housings crack from the cap bolt boss when the frame flexes under shock load. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
A housing designation on its own is not an order. State bearing, seal type, locking element and any end cover with it — a housing that lands on site with the wrong seal ring is as useless as no housing at all.
