Inch Angular Contact Ball Bearings

Inch Angular Contact Ball Bearings are designed to bidirectional load capacity of angular contact structures while adhering to inch dimension standards. Their optimized contact angles (15°/25°) flexibly balance radial/axial loads, making them ideal for high-precision, high-speed industrial equipment—especially when interfacing with inch-standard mechanical components.
Structural Features
Inch Dimension System
Strict adherence to inch-based parameters (e.g., 1.5" × 3.5" × 1.25") for seamless compatibility with European and American machinery.
Contact Angle Optimization
15°: Prioritizes high-speed, light-load scenarios (e.g., precision drives).
40°: Enhances axial load capacity for heavy-duty applications.
Material & Process
Bearings steel (AISI 52100) or stainless steel (AISI 440C) with surface quenching for hardness.
Precision grinding ensures ≤2μm roundness tolerance to reduce operational noise.
Sealing & Lubrication
Options include double-lip rubber seals (2RS) or metal shields (ZZ).
High-temperature silicone grease (-40°C~+200°C) available for extreme environments.
