Non-split Pillow Housings and Take-up Housings
One-piece housings with no cap to lift. The bearing goes in from the side and is retained by bolted covers, which makes the housing stiffer and better sealed but means the shaft must come out to change a bearing. SES holds the range as an authorised SKF distributor, covering families SBD pillow housings, THD take-up housings; construction One-piece casting with bolted end covers; bearings Spherical roller, sleeve or cylindrical bore; shaft sizes Mid range, typical conveyor sizes. Executions include SBD non-split pillow housings, THD take-up housings, executions with blind end covers, taconite-sealed executions, among others. It is specified most often into conveyor tail and take-up positions on short centres and screen and vibrating feeder supports. 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 Non-split Pillow Housings and Take-up Housings in the parts of a plant where this particular duty actually occurs. In practice that means conveyor tail and take-up positions on short centres, screen and vibrating feeder supports, mineral handling transfer conveyors, and equally bucket elevator boot shafts, chain conveyor and apron feeder tail shafts. What links them is the duty rather than the machine name — construction: One-piece, no split line. 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. Load has a strong horizontal or reversing component — The non-split housing. There is no cap joint to open under side load, which is exactly where split housings lose bore roundness. Shaft cannot be withdrawn without dismantling half the machine — A split housing instead, even at a stiffness penalty. A non-split housing in an inaccessible position turns a two-hour bearing change into a two-day one. Position is a belt take-up — The take-up variant matched to the frame slot width, with machined guide faces rather than as-cast ones. 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.
Before you commit to a non-split housing, walk the position and confirm there is room to draw the shaft out sideways. That clearance vanishes the moment somebody builds a walkway or a chute beside it, and nobody updates the drawing.
