Customization Options
170mm rubber wheels on aluminum core can usually be customized by tread material, wheel width, hardness, aluminum core geometry, fit dimensions, and mounting details. Customization is common when the wheel must match a specific machine or industrial application.
Common customization options include:
- Outer diameter and tread width
- Rubber compound or tread material
- Non-marking tread option
- Hardness adjustment
- Aluminum core profile and geometry
- Bore size or fit structure
- Custom wheel structure based on drawing or sample
- Color identification
- Wheel design for support or transport applications
Sample review and small-batch production may also be arranged depending on the wheel type and project requirement.
Engineering & Design
The wheel features a spider-web ribbed aluminum core — a structural design that reduces rotational mass while maintaining high radial load capacity. The aluminum hub is precision-machined to tight tolerances, with a bore diameter of φ47⁻⁰·⁰¹⁷/⁻⁰·⁰⁴²mm ensuring accurate fitment onto standard axle shafts with minimal play.
The solid rubber tread is vulcanization-bonded directly to the aluminum hub, creating a permanent, high-strength rubber-to-metal bond that resists delamination under continuous load cycling. The tread compound provides excellent grip on smooth and semi-rough floor surfaces while offering floor-friendly, non-marking performance.
Application Scenarios
This 170 mm rubber-on-aluminum caster wheel is engineered for use in:
- Roll containers and platform trucks in postal, e-commerce, and warehouse logistics
- AGV (Automated Guided Vehicles) and AMR drive wheels
- Industrial trolleys and hand trucks in manufacturing facilities
- Medical and hospital equipment carts requiring smooth, quiet rolling
- Airport ground support equipment and baggage handling systems
Why Choose This Wheel?
- Precision hub tolerances: Bore and step dimensions machined to ±0.015 mm, ensuring consistent axle fitment across high-volume assemblies
- Lightweight aluminum core: Up to 40% lighter than cast iron equivalents without sacrificing structural integrity
- Vulcanized rubber bonding: No adhesives — the rubber tread is chemically bonded to the aluminum hub through high-temperature vulcanization for superior durability
- Compact yet capable: At 170 mm diameter with a 50 mm tread, this wheel balances maneuverability with load distribution on standard pallet and roll-container frames
- Custom specifications available: Hub bore diameter, rubber compound (natural rubber, NBR, polyurethane), hardness (Shore A), and tread color can be adapted to OEM requirements
Manufacturer Expertise
Manufactured by a rubber-to-metal bonding specialist with over 20 years of production experience, this wheel is produced using controlled vulcanization processes, precision CNC-machined aluminum hubs, and batch-consistent rubber compounding. Products are quality-verified for dimensional accuracy, bond strength, and rolling resistance before shipment.
Frequently Asked Questions
Q: What axle diameter is compatible with the 170/50-134 wheel?
A: The hub bore is precision-machined to φ47⁻⁰·⁰¹⁷/⁻⁰·⁰⁴²mm, compatible with a standard 47 mm axle shaft with h6 or h7 tolerance class.
Q: Can the rubber tread compound be customized?
A: Yes. Standard supply uses black solid rubber. NBR (oil-resistant), natural rubber, and polyurethane treads are available on request. Shore A hardness can be adjusted between 55 and 85.
Q: Is this wheel suitable for outdoor use?
A: The standard rubber compound is suitable for indoor and covered outdoor environments. For UV-resistant or weatherproof applications, an EPDM or CR tread compound is recommended.
Q: What is the maximum load capacity?
A: Load rating depends on axle configuration and rolling speed. Please contact our technical team with your application parameters for a formal load capacity confirmation.
