Plastic and steel skate wheel lane rails for light to medium duty gravity flow — low rolling resistance wheel-on-axle lane hardware for carton, bag, tray, and bin flow lanes requiring smooth, quiet, low-friction container travel in manufacturing supermarkets and warehouse pick lanes.
Polypropylene skate wheels provide low rolling resistance, quiet operation, and corrosion resistance for cleanroom and food-adjacent environments. Steel skate wheels provide higher load capacity and resistance to heat, chemical splash, and UV exposure in industrial environments. Both wheel types run on hardened steel axles.
Skate wheel geometry provides lower rolling resistance per unit load than roller track because each wheel contacts the container base at a single point rather than along a line. This allows reliable gravity feed on shallower inclines — typically 2° to 5° — for applications where a steeper incline would cause container damage at the front stop.
Skate wheel rails are available in 25mm, 38mm, and 50mm wheel pitch — significantly denser than roller track — providing smooth container travel for bags, soft-sided totes, and trays that lack a rigid flat base and require frequent contact points to prevent deflection between support points.
Rail track widths from 2 inches to 24 inches accommodate any container width. Rail side guides are integral to the rail section, providing lateral container guidance along the full lane depth without separate guide accessories. Rail sections butt-join end to end and attach to frame support rails with standard T-slot hardware.
Skate wheel rail has a lower installed height than roller track — typically 22mm to 40mm versus 50mm to 75mm for roller track. This compact profile allows higher tier density in multi-tier rack configurations and fits in space-constrained lane geometries where roller track height clearance is not available.
ESD-dissipative polypropylene skate wheels are available for ESD-sensitive component lanes. Full polypropylene rail frames with stainless steel axles are available for food-grade and cleanroom environments where no ferrous materials are permitted in the lane.

Light corrugated carton flow lanes in warehouse pick modules and manufacturing supermarkets where skate wheel low rolling resistance provides smooth FIFO flow at minimal incline angles.
Soft-sided tote, plastic tray, and bag flow lanes where dense wheel spacing prevents container deflection between support points and provides consistent presentation at the pick face.
Food-adjacent and cleanroom component supply lanes using polypropylene rail and stainless steel axle configurations that eliminate ferrous material contact with containers and facility surfaces.
Multi-tier rack configurations and low-clearance installations where the compact skate wheel rail height profile allows higher tier density than roller track would permit.
Choose skate wheel rails over roller track when: the container is light (under 30kg), the container base is soft, flexible, or corrugated and deflects between widely-spaced rollers, the lane incline must be shallow (under 3 degrees), vertical clearance for multi-tier is limited, or the environment requires a non-ferrous contact surface. Roller track is preferred for containers over 30kg, rigid container bases, and applications requiring brake rollers for speed control.
Skate wheel rails can function on inclines as shallow as 1.5 degrees (approximately 26mm drop per 1000mm of lane depth) for light containers up to 10kg. For containers up to 30kg, a 2 to 4 degree incline is typical. The actual minimum incline depends on container weight, wheel diameter, wheel pitch, and surface cleanliness. Modular Solutions can calculate the minimum incline for any specific container and lane configuration.
Yes. Steel skate wheel rails with galvanized or powder-coated rail frames are suitable for covered outdoor environments. For fully exposed outdoor applications, stainless steel axles and UV-stabilized polypropylene wheels are specified. Polypropylene wheels may become brittle in sustained sub-zero temperatures; nylon wheels are substituted for cold outdoor applications. All outdoor installations should include a top rail cover to prevent debris accumulation on the wheel surfaces.
Rail sections butt-join with a splice plate or internal connector that aligns the rail profile and maintains continuous wheel-line contact across the joint. The splice connector is captured in the rail channel and secured with a set screw. Properly joined sections provide a smooth transition without a step or gap that would catch container edges at the joint.
Yes. Individual replacement wheels and axle kits are available for all standard skate wheel rail series. Wheels are press-fit or clip onto the axle and can be replaced individually without removing the rail section from the rack. A lane can be maintained by replacing single worn wheels as they fail rather than replacing the entire rail section, significantly reducing maintenance cost per lane over the rack service life.
