Material Handling & Logistics Solutions

Stainless & Galvanized Steel Gravity Conveyor Rollers

Engineered for gravity roller tracks, manual assembly benches, sorting lines, and powered conveyor systems. Precision-machined with versatile shaft configurations to fit various frame profiles.

Galvanized and stainless steel gravity conveyor rollers with multiple shaft ends

Custom shaft ends (external thread, female thread, milled flat slot)

Precision-cut seamless carbon steel and stainless roller shell

Smooth Rolling Performance & Flexible Mounting

Our unpowered and gravity conveyor rollers provide low starting torque and quiet running under continuous warehouse and factory operation. High-precision ball bearings and rigid steel shells ensure excellent concentricity and extended service life.

Custom Shaft Machining

Configurable with male threads, internal female threads, milled flats, or spring-loaded pins for rapid drop-in installation.

Surface Finishes

Zinc electroplated, hot-dip galvanized, polished stainless steel (201/304/316), or black oxide steel tube options.

High Load Stability

Reinforced bearing housings with steel retaining rings withstand repeated carton, pallet, and tote box impact.

Frequently Asked Questions

Q1: How do I choose the correct shaft installation method?
Spring-loaded shafts allow fast tool-free drop-in; milled flats fit slot-punched conveyor side frames; threaded shafts provide rigid, bolt-tightened structural rigidity.

Q2: What is the maximum load capacity per roller?
Load capacity ranges from 30 kg to 350 kg per roller depending on tube diameter, wall thickness, shaft size, and face length.

Q3: Can rollers be supplied with rubber or PU sleeves?
Yes. We can apply soft PVC, polyurethane, or vulcanized rubber sleeves to prevent scratching on delicate carton/goods surfaces.
