Conveyor Pulley Housing
Housings designed around belt conveyor pulley shafts: sealed for coal, ore and clinker dust, sized for the shaft diameters conveyor pulleys actually use, and arranged so the seal can be purged in service. SES holds the range as an authorised SKF distributor, covering family SDVD; bearings Spherical roller, sleeve or cylindrical bore; shaft sizes Conveyor pulley range, mid to large; sealing Taconite and labyrinth, with purge. Executions include SDVD series housings, taconite-sealed executions, cast steel executions, housings with blind end covers, among others. It is specified most often into drive, head, tail, bend and snub pulleys in coal handling and iron ore and pellet plant belt conveyors. 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 Conveyor Pulley Housing in the parts of a plant where this particular duty actually occurs. In practice that means drive, head, tail, bend and snub pulleys in coal handling, iron ore and pellet plant belt conveyors, clinker and raw meal conveyors in cement plants, and equally overburden and coal conveyors at mine sites, port and terminal bulk handling belts, ash and sinter handling conveyors in steel and power. What links them is the duty rather than the machine name — duty: Belt conveyor pulley shafts. 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. Belt tension gives a high, largely constant radial load in one direction — Base bolts in fitted holes able to take shear, or a location key. The load direction on a conveyor pulley never reverses, and it will walk a loosely bolted housing. Housing sits at a transfer point under continuous spillage — Taconite sealing with an external purge line brought out to a serviceable point, so the seal cavity can be refilled without digging the housing free. Pulley shaft is stepped for the locking element — The housing to the bearing seat diameter, and confirm the seal bore matches the adjacent shaft step rather than the seat. 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.
Fit pulley bearings as a locating and non-locating pair even on short conveyors. Two located ends on a lagged drum is the classic reason pulley bearings run warm from commissioning and nobody can explain why.
