INA EGB 2015 E40 B - Maintenance-Free Bearing Sleeve 20×23×15 mm

Industrial Applications & Use Cases

The INA EGB 2015 E40 B plain bearing sleeve is engineered for demanding industrial applications where a maintenance-free, low-friction, self-lubricating bearing solution is required. Its compact 20 mm inner diameter, 23 mm outer diameter, and 15 mm width suit shafts, pivots, linkages, actuators, conveyors, and mechanical joints across many sectors — manufacturing, automation, hydraulics, agricultural and construction machinery.

This sleeve is ideal wherever conventional ball bearings or roller bearings are impractical due to limited space, contamination risk, or lack of regular maintenance. It excels in environments with dust, dirt, moisture, or temperature extremes, offering a reliable alternative to traditional bearing units.

Technical Construction & Performance Advantages

• Metal-polymer composite plain bush — combines strong steel backing with a polymer sliding layer (E40), delivering low friction, excellent wear resistance, and long service life under varied operating conditions.

• Very wide operating temperature range (-200 °C to +280 °C) — ensures stable performance in both cryogenic environments and high-temperature systems.

• High load capacity — rated for 42 000 N dynamic and 75 000 N static radial load, making it suitable for heavy-duty shafts, oscillating pivots, and heavily loaded mechanical joints.

• Maintenance-free operation — no lubrication required, eliminates downtime and reduces operational costs.

• Compact dimensions (20×23×15 mm) — ideal for retrofits, tight assemblies, or design where footprint is limited but durability is critical.

These features make EGB 2015 E40 B a robust, reliable bearing sleeve alternative to rolling bearings when lubrication and maintenance are problematic or impossible.

Key Benefits for B2B Buyers

• Reduced maintenance costs and downtime — no lubrication, no greasing schedules.

• Extended service life under harsh conditions — ideal for dusty, wet, high-temperature or corrosive environments.

• Versatile use across industries — automation, hydraulics, conveyors, construction, agriculture, machinery.

• Compact and easy to integrate — suitable for compact shafts, pivots, hinges, and mechanical linkages.

• Cost-effective bearing solution — combines low friction, high load capacity and minimal upkeep in one component.

FAQ

Is INA EGB 2015 E40 B suitable for shafts exposed to dust, dirt or water?
Yes — the metal-polymer composite sliding layer and lack of lubrication requirements make it ideal for harsh environments where contamination may impair rolling bearings.

Can this bearing sleeve replace a roller or ball bearing?
Yes — in many applications it can, especially where oscillating motion, limited maintenance options, or compact dimensions matter more than extremely high rotational speeds.

What shaft diameter does it fit?
It fits shafts with 20 mm diameter (inner diameter of sleeve).

Do I need lubrication or maintenance?
No — the E40 polymer layer is self-lubricating, so the sleeve is maintenance-free under standard operational conditions.

Is it suitable for heavy loads?
Yes — with radial dynamic load rating up to 42 000 N and static load rating 75 000 N, it can handle significant loads in shafts, pivots and mechanical joints.
