Frequently Asked Questions: VX – V-Groove Ultra High Capacity Polymer Wheel

What are VX V-Groove Ultra High Capacity Polymer Wheels?
VX V-Groove Ultra High Capacity Polymer Wheels from Caster City are heavy-duty, non-marking black polymer caster wheels designed for precise tracking on angle iron or round bar rails. Available in 4×2, 5×2, 6×2, and 8×2 inch sizes, they feature a 7/16-inch deep, 7/8-inch wide V-groove for secure guidance. Each wheel supports up to 2000 pounds, outperforming ductile steel wheels in the same footprint. Compression-molded and machined, they resist flat spots, delamination, chemicals, oils, and acids. Equipped with 2–4 high-efficiency  precision sealed ball bearings with a 1/2-inch inner diameter (ID), they offer maintenance-free, smooth, and quiet operation but may corrode in wet or harsh environments. They operate from -20°F to 250°F, ideal for warehousing, manufacturing, aerospace, automotive, food processing, and marine settings.

What makes these wheels different from standard caster wheels?
Unlike standard polyurethane or metal wheels, VX V-Groove Polymer Wheels combine a V-groove for track guidance with non-marking polymer that protects floors. Their 2000-pound capacity surpasses steel in the same size, and compression molding prevents flat spots under static loads. With 80 Shore D hardness, they resist chemicals and impacts better than steel, though  bearings may rust in wet conditions. The high-efficiency sealed bearings with a 1/2-inch ID ensure maintenance-free, quiet, and smooth rolling, making them perfect for precise industrial tasks.

• V-Groove Dimensions: 7/16-inch depth, 7/8-inch width for secure track guidance.
• Hardness: 80 Shore D for toughness without floor damage.
• Temperature Range: -20°F to 250°F, with an approximate melting point of 500°F.
• Bearings: two high-efficiency  precision sealed ball bearings, 1/2-inch ID, maintenance-free but prone to rust in corrosive environments.
• Tread Face: Flat on groove sides for stable load distribution.

What applications are these wheels best suited for?
These wheels excel in heavy-duty settings requiring guided movement or floor protection:

• Material Handling: Moving pallets or bins in warehouses along tracks.
• Manufacturing: Guiding assembly line carts or automated guided vehicles (AGVs).
• Aerospace: Transporting tools or components precisely.
• Automotive: Hauling frames or parts on production lines.
• Food Processing: Rolling bins in clean environments (note bearing rust risk).
• Marine: Towing crates in salty docks (avoid prolonged wet exposure).
• Chemical Plants: Handling vats in harsh, chemical-heavy settings.

They work on smooth indoor floors or elevated tracks, resisting shocks and debris, but chrome plated bearings require caution in corrosive environments.

Can these wheels be used off tracks?
Yes, VX V-Groove Polymer Wheels roll smoothly on flat, smooth surfaces when not on tracks. The flat tread face on either side of the groove ensures stable load distribution, preventing tipping or wobbling. Their non-marking polymer protects floors, making them versatile for platform trucks, sliding barn doors, or free-rolling carts, with the V-groove ready for track use when needed.

How do these wheels compare to ductile steel wheels?
VX V-Groove Polymer Wheels outperform ductile steel wheels by supporting the same 2000-pound capacity in a similar footprint while being lighter and non-marking, protecting floors from scratches or dents. The polymer resists chemicals and impacts better than steel, which may dent or rust. Compression molding prevents flat spots, unlike steel under static loads. The high-efficiency sealed bearings (1/2-inch ID) reduce noise and vibration for smoother, maintenance-free operation, though they may corrode in wet settings.

What environments are these wheels suitable for?These wheels thrive in demanding environments due to their robust polymer design. They resist:

• Chemicals: Acids, oils, greases, and corrosive substances.
• Temperature Extremes: From -20°F to 250°F, suitable for cold storage or high-heat ovens.
• Corrosion: Polymer resists corrosion, but chrome bearings will rust in wet or salty conditions.

These industrial caster wheels are ideal for warehouses, factories, food processing plants, and chemical facilities, but avoid prolonged exposure to moisture due to bearing corrosion risk.

What bearing options are available?
Each “VX” V-Groove Wheel comes with two, high-efficiency precision sealed ball bearings, each with top hat spanners for a 1/2-inch ID. These bearings are maintenance-free, keeping out dust and debris for long-lasting, smooth performance. However, they may corrode in wet or corrosive environments like marine docks or food processing plants. No other bearing options are available for this model. Contact Caster City at 800-501-3808 for guidance on managing corrosion risks.

How do the V-groove dimensions affect performance?
The 7/16-inch deep and 7/8-inch wide V-groove ensures secure engagement with angle iron or round bar tracks. The depth locks the wheel on the rail, preventing derailment, while the width provides a firm grip for stable tracking. The flat tread on either side balances the load, reducing wear and ensuring smooth rolling on tracks or floors, even with slight unevenness.

Can these wheels handle static loads?
Yes, the compression-molded polymer design prevents flat spots and delamination, common issues with polyurethane wheels under prolonged static loads. The 80 Shore D hardness and straight-sided construction distribute weight evenly, ensuring the wheels maintain shape and performance under heavy loads up to 2000 pounds.

Are these wheels customizable?
Customization is limited to specific configurations like track design or load requirements, as the bearing option is fixed to high-efficiency precision sealed ball bearings with a 1/2-inch ID. The polymer material and V-groove specs are standard, but Caster City can tailor solutions for unique applications, such as high-temperature settings up to 250°F. Contact the engineering team at 800-501-3808 for custom needs.

How do I maintain these wheels?
VX V-Groove Polymer Wheels are low-maintenance due to their high-efficiency sealed bearings and durable polymer construction. The sealed bearings (1/2-inch ID) prevent dust and debris buildup, eliminating the need for regular lubrication or cleaning. To ensure longevity:

Clean Regularly: Wipe off debris, oils, or chemicals to prevent buildup.

Inspect Tracks: Keep rails free of debris for optimal tracking.

Avoid Overloading: Stay within the 2000-pound capacity per wheel.

Monitor Corrosion: In wet or corrosive environments, check chrome bearings for rust and consider protective measures.
