Ball-bearing pivot hinge 28×100 mm ZAW TOC 28S – roller pivot hinge with ball, 28 mm diameter, 100 mm length

A ball-bearing pivot hinge ZAW TOC 28S with a 28 mm pivot diameter and 100 mm overall length is designed for rotational mounting where low friction and smooth, controlled movement are required. The integrated ball mechanism distributes load across the pivot, improving wear characteristics and ensuring consistent operation for doors, cabinet flaps, access panels and light industrial applications. The compact cylindrical form and standard dimensions allow discreet installation in furniture frames and lightweight metal assemblies.

Advantages

The ball-bearing design reduces friction and provides smoother pivoting compared with plain pivots, extending service life and reducing noise during operation. Its 28 mm diameter and 100 mm length deliver stable support for medium-duty panels while the internal ball mechanism helps maintain alignment and consistent movement under repeated cycles. The simple cylindrical shape allows easy mounting in drilled holes or housings and is suitable for both wooden and metal structures.

Suitable for

• Cabinet doors and furniture flaps that require smooth pivoting
• Access panels and inspection hatches in light industrial equipment
• Interior doors in lightweight constructions and service enclosures
• Retrofit or replacement applications where a 28 mm pivot diameter is specified

When it may not be suitable

This pivot hinge is intended for medium-duty tasks and light industrial use; it is not designed for heavy structural doors, high-load exterior entrance doors or applications requiring high-security locking. Environments with continuous heavy vibration, abrasive contaminants or prolonged exposure to corrosive agents may shorten its service life unless additional protection or specialized materials are used.

Key specifications

• Pivot diameter: 28 mm
• Overall length: 100 mm
• Bearing type: integrated ball-bearing mechanism for reduced friction
• Intended use: rotational pivot for doors, flaps and access panels
• Mounting style: cylindrical pivot for insertion into drilled housings or sleeves

How to use

Drill or prepare a cylindrical housing with dimensions matching the 28 mm pivot diameter and the installation depth required for the 100 mm length. Insert the pivot hinge into the prepared hole or sleeve and secure according to the surrounding construction (press-fit, retaining clip or set screw as applicable). Align the mating component so the pivot rotates freely within its housing and test the movement through its full range to ensure smooth operation. Periodic inspection for dirt, wear and proper lubrication will maintain reliable performance.

What to consider before purchase

• Verify that a 28 mm pivot diameter and 100 mm length match your mounting holes and depth.
• Confirm the hinge is suitable for the expected load and duty cycle of your application.
• Assess environmental conditions (moisture, corrosive agents, dust) and consider protective finishes or different materials if needed.
• Check compatibility with the surrounding frame material and required fastening method.

Usage recommendations

For best performance, install the pivot hinge in a precisely machined housing, keep the bearing area clean, and apply light machine oil or grease at intervals appropriate for the operating environment. Avoid overloading beyond medium-duty limits and inspect periodically for wear to ensure continued smooth pivoting.
