Therwen Conveyor Rollers 1.5in dia x 10in long — 4 Sets with Galvanized Steel and Spring-Loaded Brackets

Therwen 4 sets of 1.5" diameter, 10" long spring-loaded conveyor rollers with brackets provide a ready-to-install solution for light-to-medium duty material handling and kayak or boat support.

These replacement rollers come as four complete sets (four rollers and four matching brackets) built from galvanized steel with corrosion-resistant coating. Each roller measures about 10 inches (250 mm) of tube surface length and 1.5 inches (3.81 cm) in diameter, with a 12 mm shaft—specifications chosen to balance load capacity, durability and compatibility with many stands, rollers and dock or loading systems.

How much weight can each Therwen roller support?

Each roller is rated to handle approximately 90 pounds, making the set suitable for many light-to-medium load applications such as kayak loading, utility stands or packaging conveyors. The galvanized steel construction and anti-corrosion finish help maintain load capacity in damp or outdoor conditions.

• Single roller load capacity: ~90 lbs (per set component).
• Material: galvanized steel with rust-resistant coating for outdoor use.
• Ideal for individual items like kayaks, bikes, boxes or small assemblies.
• Not designed for heavy industrial lines requiring thousands of pounds of support.

What features make installation and removal easier?

These rollers include a spring-loaded shaft on one side so you can remove or replace a roller quickly without disassembling the entire bracket. The paired brackets are sized to accept the 12 mm shaft and provide secure mounting while still allowing the spring mechanism to compress for rapid servicing or replacement.

• Spring-loaded shaft on one side for quick removal and replacement.
• 12 mm shaft diameter fits standard brackets and supports.
• Brackets included—no separate purchase required for basic installation.
• Compact 10" roller length fits common conveyor and stand widths.

Which applications are these rollers best suited for?

The Therwen rollers are versatile and can serve multiple uses from DIY boat and kayak rollers to replacement parts for saw stands, roller stands, unloading ramps and small packaging conveyors. Their moderate load rating and protective finish make them appropriate for workshop, dockside or garage environments where occasional exposure to moisture or abrasion occurs.

• Boat and kayak loading/unloading rollers and dock bumpers.
• Replacement rollers for roller stands, saw stands and material stands.
• Small conveyor lines for light packaging or assembly areas.
• Bike rollers, utility carts and similar hobbyist or light-commercial uses.

How do the dimensions affect compatibility with my equipment?

The roller tube measures ~10 inches of usable surface length and 1.5 inches in diameter, with a 0.47-inch (12 mm) shaft diameter—dimensions that match many common small-stand and dock roller designs. Confirm your existing bracket spacing, shaft clearance and desired contact width before installation to ensure the roller aligns with mounting holes and contact areas.

• Roller surface length: approx. 10" (250 mm) for mid-width coverage.
• Tube diameter: 1.5" (3.81 cm) for stable contact and load distribution.
• Shaft: ~12 mm (0.47")—measure your bracket bore to confirm fit.
• Surface thickness: 1.2 mm for durability under moderate wear.

Who this is for: The Therwen 4-set package is aimed at homeowners, small business owners and hobbyists who need a compact, reliable set of replacement rollers and brackets for kayak and boat handling, light conveyor tasks, or workshop stands. If you need a modest load rating with easy serviceability and corrosion resistance for outdoor or garage use, this kit provides a convenient, ready-to-mount solution.
