Bearing Bushes

Bearing bushes for tail gates – Durable bearing points for precise and reliable motion

In the joint connections of a tail gate, bearing bushes fulfil a key structural function. They act as wear-resistant bearing points for bolts and moving assemblies and stabilise force transfer throughout the mechanical structure. In this category, you will find bearing bushes designed for the requirements of modern lifting arms, pivot mechanisms and cylinder mounting points on lift gates. SULEJ Ladebordwand uses certified components that support precise guidance and long-term stability of the bearing points.

Function and design – Bearing bushes as controlled guidance elements

Bearing bushes belong to the core mechanical elements of a tail gate. They guide the pins that connect lift arms, brackets and cylinder mounts. Their material characteristics reduce friction, distribute forces across larger surfaces and protect the mounting points from structural wear. At the joint positions of a tail lift, dynamic loads act on the bearing seats depending on lift position, load and movement direction. Bearing bushes hold these forces within the defined bearing area and provide stable motion control. Without suitable bushes, pins would run directly in the surrounding structure of the tail gate, which can lead to abrasion, noise and damaged bearing points.

Materials and variants – Technical solutions for pin and joint interfaces

Different bush materials are available for the various bearing points of a tail lift system. These include traditional bearing bushes as well as sliding bushings for dynamically loaded joints.

• Steel bushes: Hardened steel bushes provide high pressure and wear resistance. They are used at heavily loaded joints such as the main bearings of lift arms. Reliable lubrication is required to minimise friction and surface wear.
• Bronze and sintered metal bushes: These materials offer stable sliding properties and are suitable for bearing points exposed to dynamic loads. Sintered bushes can absorb lubricant in their porous structure and gradually release it to the contact surfaces during operation.
• Composite bushes made of polymer or fibre-reinforced materials: These variants are corrosion-resistant, lightweight and often low-maintenance. They reduce lubrication requirements and are suitable for medium-load or difficult-to-access bearing points.

A suitable bush ensures that every mechanical connection between pin and bearing point transfers forces correctly without undesired deformation. The selection depends on load patterns, movement frequency, installation situation and environmental conditions at the respective bearing interface.

Inspection and maintenance – Detecting bearing wear at an early stage

Regular inspections of the joints on the lift gate are essential for early detection of wear. Visual checks of bearing play, surface contact areas and pin condition provide the first indications of material changes. Increasing bearing play, enlarged contact zones or irregular motion of the tail gate indicate progressing bush wear. Lubrication is a key element in maintaining a tail lift. Adequate grease reduces friction, prevents contamination and protects pins and inner surfaces of the bush from corrosion. Timely replacement of worn components prevents consequential damage to lift arms, cylinder mounts and further mechanical bearing points.

Manufacturing quality – Requirements for bearing points of a lift gate

Bearing bushes must meet strict requirements regarding dimensional accuracy, material quality and surface finish. Precisely machined inner surfaces ensure even load distribution and defined bearing play. Burr-free contact areas and correct manufacturing tolerances reduce friction and enable smooth mechanical motion. In a lift gate, varying forces and load peaks act on the bearing interfaces over the entire movement cycle. The bearing bushes offered here are selected based on fit accuracy, wear behaviour and structural durability to ensure long-term stability. SULEJ Ladebordwand focuses on technically appropriate components that meet the demands of daily operation.

Frequently asked questions about bearing bushes for lift gates (FAQ)

When do bearing bushes need to be replaced?

Replacement is necessary if bearing play increases, motion of the tail gate becomes irregular or visible material wear appears on bushes and pins.

Can I replace bearing bushes myself?

Replacement requires suitable tools and experience with bearing points. Correct alignment is essential to avoid damaging the mounting seats.

Which bearing bush fits my tail lift?

Selection depends on installation dimensions, load profile and the specific assembly. Technical drawings, type plates or measurement data provide the necessary information.

Which materials are used?

Steel, bronze, sintered metal and composite materials are used. The choice depends on load conditions, lubrication requirements and environmental factors at the bearing point.

What happens if bearing bushes are worn?

Worn bearing bushes increase play in the joint and can cause structural wear on pins and mounting points. Timely replacement stabilises movement and protects the mechanical assemblies.
