Overview
Custom 316L Washdown Bearing Housings for Food Conveyors
ZSCNC machines stainless steel bearing housings to customer drawings for food conveyor assemblies. Our Wuxi machining base focuses on CNC milling and turning. Housing dimensions, material, bearing fit and surface requirements are confirmed for each order.
Made to OEM Drawings
Send the approved drawing revision, 3D model, bearing designation, quantity and delivery requirements. Flanged, pillow-block and take-up housing geometries are reviewed for tool access, workholding and inspection before quotation. Replacement fit depends on the approved interfaces and the assembled conveyor.
Bearing Bore Fit and Mounting Features
Bores, Datums and Shaft Center Height
The bearing fit must follow the customer's bearing selection and operating conditions. We do not apply H7, JS6 or K7 to every housing. Specify bore diameter, fit, roundness requirements, mounting datum, shaft center height and hole-position tolerances on the drawing.
Seal Lands and Retaining Features
Define seal-register diameter, shoulder location, retaining-groove dimensions, surface texture and entry-edge detail. The seal system and bearing arrangement are selected and validated by the equipment designer.
Drainage and Cleaning Access
Slopes, drain holes, corner radii and standoff dimensions are machined when shown on the approved drawing. They depend on installation orientation and cleaning access; there is no universal drainage angle or minimum radius for all housings.
| Feature | Required drawing information |
|---|---|
| Bearing bore | Diameter, fit and geometric requirements |
| Mounting interface | Hole pattern, position tolerance, base flatness and datum scheme |
| Seal land | Diameter, surface texture and edge detail |
| Drainage features | Geometry, orientation and access for cleaning |
316L Material and Surface Treatment
316L is a customer-specified material option. Its suitability depends on cleaning chemistry, chloride exposure, temperature and the operating environment. Stainless steel grade alone does not guarantee corrosion resistance, food-contact compliance or cleanability.
Passivation or electropolishing requirements should be included in the RFQ. The process route, resulting finish and inspection criteria are confirmed before order acceptance. Required material documentation and traceability are also confirmed for the selected stock; certificates are not assumed to be included.
CNC Milling, Turning and Inspection
Turning produces bearing seats and seal registers; milling produces mounting faces, holes, slots and accessible drain features. Our Wuxi base has no in-house 5-axis machining, EDM or wire cutting. Features beyond the confirmed milling and turning scope require a separately agreed process route.
Critical bore sizes, mounting positions, center heights and specified surface requirements form the inspection plan. Measurement method, reporting scope and acceptance criteria are agreed for the order. See our quality inspection information.
Application and Assembly Validation
We review drawing-based housings for meat, seafood, dairy, beverage, bakery and packaging conveyors. Bearing life, sealing, washdown resistance and conveyor alignment depend on the complete assembly and operating conditions. IP69K applies only where the relevant assembled product has supporting testing; a machined housing is not automatically IP69K-rated.
