Component Specifications

Definition
Bearings and bushings are critical mechanical components designed to constrain relative motion to only the desired motion while reducing friction between moving parts. In drive motors and solenoids, they support rotating shafts or linear rods, ensuring smooth operation, precise alignment, and load distribution. Bearings typically handle rotational motion with rolling elements (ball, roller), while bushings (plain bearings) provide sliding surfaces for linear or oscillatory motion with lubrication.
Working Principle
Bearings operate on the principle of replacing sliding friction with rolling friction (using balls or rollers) or maintaining a lubricated film (in bushings) to minimize energy loss, wear, and heat generation. They support radial and axial loads, maintain clearance tolerances, and enable efficient power transmission by allowing controlled movement with minimal resistance.
Materials
Common materials include chrome steel (AISI 52100), stainless steel (440C), ceramic (silicon nitride), bronze (SAE 660), brass, polymer composites (PTFE, nylon), and sintered metals. Selection depends on load capacity, speed, temperature, corrosion resistance, and lubrication requirements.
Technical Parameters
  • Clearance C3 (loose) to C0 (tight) for radial bearings
  • Lubrication Grease, oil, or dry (self-lubricating bushings)
  • Speed Rating Up to 20,000 rpm for ball bearings
  • Load Capacity Dynamic: 5-50 kN, Static: 10-100 kN
  • Precision Class ABEC 1-9 (ISO P0-P2)
  • Temperature Range -40°C to +150°C (standard), up to 300°C (high-temp variants)
Standards
ISO 15, ISO 76, ISO 281, DIN 625, DIN 316

Frequently Asked Questions

What is the difference between bearings and bushings?

Bearings use rolling elements (balls/rollers) for rotational motion with lower friction, while bushings are sleeve-type plain bearings that provide a sliding surface, often used for linear or oscillatory motion with lubrication.

How often should bearings in drive motors be replaced?

Replacement intervals depend on operating conditions (load, speed, temperature), but typically range from 10,000 to 50,000 hours. Regular vibration analysis and lubrication monitoring can predict failures.

Can bushings operate without lubrication?

Yes, self-lubricating bushings made from materials like PTFE or bronze with graphite inserts can operate dry, but most metal bushings require periodic lubrication to prevent wear and overheating.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
