Products Description
The 4 inch rigid caster is a fixed mobility solution engineered for industrial carts, equipment, furniture, and commercial applications. With a 140kg load capacity per caster and rigid construction for straight-line tracking, this caster provides reliable support with stable, controlled rolling performance and exceptional durability - essential for environments where directional stability and secure attachment are priorities.
The impact on your daily operations: When industrial carts, equipment, and furniture need to be moved in straight lines for transport, loading, or positioning, rigid casters provide the directional stability that swivel casters cannot. By eliminating unwanted swiveling, rigid casters keep equipment tracking straight - reducing effort for operators and improving safety during transport. The solid rubber wheel delivers quiet, non-marking rolling with excellent shock absorption, protecting floors and reducing noise in workshops and commercial environments. The Double Ball Bearing ensures smooth rolling with minimal friction, making heavy loads easier to move with controlled effort. The 100mm diameter with 36mm width provides good load distribution and rolling efficiency.
The solid rubber wheel offers excellent shock absorption, quiet operation, and floor protection - making it ideal for industrial and commercial applications where vibration dampening and noise reduction are priorities. Unlike hard plastic or nylon wheels that transmit vibration, rubber provides a cushioned ride and smooth rolling performance. Unlike pneumatic tires, solid rubber requires no maintenance and is immune to punctures, providing reliable performance in demanding environments. Optional wheel materials (PU, Nylon, PP) are available for applications with specific wear resistance, chemical resistance, or floor protection requirements.
Available with top plate mounting for secure attachment to carts, equipment, and furniture. Available in 4″ and 5″ diameters with multiple wheel material options and Double Ball Bearing as standard. The rigid (fixed) design ensures straight-line tracking - making this 4 inch rigid caster the ideal choice for applications requiring controlled, directional movement where swiveling is not desired.

FAQ
Q1: What is the load capacity of this 4 inch rigid caster?
A: This 4 inch rigid caster has a load capacity of 140 kg per caster. For carts, equipment, or furniture with four casters, the total capacity is 560 kg. However, please note that the effective load per caster should be calculated as Total Load ÷ 3 (allowing for uneven weight distribution) rather than Total Load ÷ 4.
Q2: What is the difference between a rigid caster and a swivel caster?
A: A rigid caster (featured here) rolls only in a straight line - providing stable, controlled movement and eliminating unwanted swiveling. A swivel caster rotates 360° - offering maneuverability and steering capability. For carts and equipment, rigid casters are typically used on the rear for tracking and stability, while swivel casters are used on the front for steering. This combination provides both maneuverability and directional control.
Q3: What are the advantages of solid rubber wheels?
A: Solid rubber wheels offer: Superior shock absorption - cushions impacts and smooths out uneven surfaces; Quiet operation - significantly reduces rolling noise; Floor protection - non-marking and gentle on floors; Good traction - provides grip on various surfaces; No maintenance - no air pressure to check or maintain; Puncture-proof - immune to flats and leaks. These characteristics make solid rubber ideal for industrial and commercial applications.
Q4: What wheel material options are available for this caster?
A: This caster series is available with four wheel material options: Solid Rubber - standard option offering superior shock absorption and quiet operation; PU - excellent wear resistance and floor protection; Nylon - superior impact resistance and durability; PP - lightweight and chemical-resistant. Choose based on your load, floor type, and application requirements.
Q5: What is the advantage of the Double Ball Bearing?
A: The Double Ball Bearing provides: Smooth rolling - low rolling resistance for effortless movement; Reduced friction - less wear on bearing components for extended service life; Even load distribution - two rows of balls distribute load more evenly, reducing stress on each bearing. This bearing type is ideal for applications requiring smooth, reliable performance under heavy loads.
Q6: What equipment is this 4 inch rigid caster suitable for?
A: This 4 inch rigid caster is suitable for: Industrial carts - workshop carts, service carts, and utility carts (rear position); Equipment - mobile equipment and machinery stands; Furniture - heavy furniture, worktables, and fixtures; Warehouse equipment - warehouse carts and trolleys (rear position); Commercial equipment - retail fixtures and display stands.
Q7: Is this a steel caster?
A: This caster features a solid rubber wheel with a zinc-plated steel bracket - the bracket is made of steel for structural strength and durability. For applications requiring stainless steel casters or specific metal wheels, please contact our sales team for alternative configurations.
Q8: Is this caster suitable for heavy duty applications?
A: Yes. This caster is designed for heavy duty applications with a 140kg load capacity per caster, a solid rubber wheel for shock absorption, and a Double Ball Bearing for smooth performance. It is suitable for industrial carts, equipment, and furniture requiring reliable, durable mobility in straight-line applications.
Q9: What is the mounting specification for this caster?
A: This caster uses top plate mounting for secure attachment. The robust top plate design ensures stable load distribution and reliable performance. Please contact our sales team for detailed plate dimension specifications and bolt hole patterns to confirm compatibility with your equipment.
Q10: What are the available sizes for this caster series?
A: This caster series is available in 4-inch and 5-inch diameters. The 4-inch option (featured here) offers a compact size with a 130mm load height - ideal for applications where space is limited. The 5-inch option provides better rolling efficiency over floor transitions and a higher load height.
Q11: What certifications does Xingteng hold?
A: Xingteng holds ISO 9001:2015 Quality Management certification, TUV Product Certification for multiple product series, and RoHS 2.0 environmental compliance. We are also a recognized AA-level "Contract-Honoring and Credit-Worthy Enterprise" in Zhejiang Province.
