Product Description

Component	Material	Material Advantages
Inner and Outer Rings	High - quality bearing steel	Exceptional hardness, wear resistance, fatigue strength; provides a robust structure
Rolling Elements	Premium bearing - grade steel	High hardness and toughness, suitable for withstanding heavy loads during rotation
Bearing Cage	Brass or high - performance engineering plastics	Brass: good corrosion resistance, high - temperature stability; Plastics: lightweight, reduce friction, suitable for high - speed applications

Technical Requirements:

Roundness of inner and outer rings maintained within a few microns for smooth rotation and reduced vibration.
Surface finish of raceways with roughness value Ra 0.1 - 0.2 μm to minimize friction and wear.
Designed to operate at high speeds (up to tens of thousands of revolutions per minute).
Capable of withstanding significant radial and axial loads (e.g., medium - sized bearing: radial load of several thousand Newtons, axial load of several hundred Newtons).

Quality Assurance:

Rigorous inspection of raw materials for chemical composition and mechanical properties.
Dimensional inspections at multiple manufacturing stages.
Comprehensive performance tests including high - speed running, vibration, noise, temperature rise, and load - carrying capacity assessment.

Component	Material	Material Advantages
Seal Body	Nitrile rubber (NBR), Fluorocarbon rubber (FKM), or Silicone rubber	NBR: Excellent resistance to oils, fuels, and common chemicals. FKM: Superior heat, chemical resistance, and low - temperature flexibility. Silicone rubber: Good electrical insulation, wide - temperature range suitability
Reinforcing Material	Fabric or metal inserts	Enhance mechanical strength and durability of the seal

Technical Requirements:

Provide reliable leak - tight seal under different pressures (e.g., up to several hundred bar in hydraulic systems).
Operate in a wide temperature range (- 50°C to + 250°C depending on material).
Have good wear resistance for continuous movement and friction applications.
Maintain sealing integrity over an extended period in aggressive chemical or extreme - temperature environments.

Quality Assurance:

Thorough testing of raw materials from reputable suppliers.
Careful molding and curing during manufacturing for proper shape and dimensional accuracy.
Series of tests including pressure, temperature cycling, and chemical resistance; visual inspections for defects.
