3 Inch Black Color High Quality PVC M10*20 Double Ball Bearings Swivel Caster - Easy Assembling For Equipments and Machines
This caster is a durable, medium-duty mobility solution engineered for straightforward installation on equipment and machinery. Its key features and their functions are:
| Feature | Functional Description | Purpose |
|---|---|---|
| 3-inch (75mm) Black PVC Wheel | Wheel diameter of approximately 75mm, made from durable black Polyvinyl Chloride (PVC) . | Provides a hard-wearing, impact-resistant surface with good load-bearing capability. PVC is resistant to oils, grease, and many chemicals, ensuring longevity. The black color is practical for industrial settings, hiding dirt and wear effectively. |
| M10 x 20 Threaded Stem | Mounting type is a threaded stem with M10 diameter and approx. 20mm length. | Enables easy and secure assembly directly into equipment with matching threaded holes. The threaded design provides a strong, reliable attachment that resists loosening during operation. |
| Double Ball Bearings | Precision double ball bearings in the swivel head. | Ensures ultra-smooth 360° rotation and effortless maneuverability, even when supporting heavy equipment. This design significantly reduces pushing effort and ensures long-term reliable performance. |
| Swivel (360° rotation) Mechanism | Full swivel design allows continuous rotation in any horizontal direction. | Enables omnidirectional maneuverability – the caster instantly aligns with the pushing force, making it easy to navigate tight spaces and change direction without extra effort. |
| Medium-Duty Load Capacity | Typical load capacity ranges from 60 kg to 95 kg (approx. 130 lbs to 210 lbs) per caster. | Provides dependable support for medium-weight equipment and machinery, ensuring safe and stable mobility. |
| Non-marking Tread | The PVC surface is designed to be floor-friendly. | Prevents scratches, scuffs, and black marks on floors, making it suitable for indoor environments where floor protection is important. |
This caster offers the following key advantages for equipment and machine mobility:
Effortless Maneuverability – The combination of a 360° swivel and double ball bearings allows for smooth, low-effort movement in any direction. Operators can easily reposition heavy equipment with minimal physical strain.
Easy and Secure Assembly – The M10 threaded stem design simplifies mounting directly onto compatible equipment. The threaded connection provides a firm, reliable attachment that stays secure during operation.
Durable and Reliable – PVC construction resists impacts, oils, and many chemicals, ensuring a long service life even in demanding industrial or commercial environments. The black finish also hides wear and tear.
Quiet and Floor-Friendly – The smooth PVC tread rolls quietly and leaves no marks, protecting sensitive floors such as polished concrete, wood, and tile.
Low Maintenance – Double ball bearings reduce friction and wear, meaning less frequent lubrication and replacement compared to plain-bearing casters.
Versatile Load Handling – With a typical capacity of 60–95 kg per caster, these wheels are ideal for a wide range of medium-duty applications, from workshop carts to industrial equipment.
Thanks to its threaded stem mounting and durable construction, this caster is ideally suited for equipment and machines that require secure, easy-to-install mobility solutions, including:
Industrial & Workshop
Machinery dollies and equipment carts
Tool carts and workstations
Assembly line carts and conveyor systems
Hand trucks and platform trucks
