FEATURED · ANGULAR CONTACT
Featured · Angular Contact Bearings
Angular contact ball bearings carry combined radial and axial loads, and are a key support in high-precision linear drives and positioning mechanisms. The exploded views show where the bearings sit in each assembly.
BALL SCREW
Ball Screw
A matched pair of angular contact bearings supports the screw end, carrying bi-directional axial load with high running accuracy.
SUPPORT UNIT
Support Unit
The BK/BF support unit houses a matched pair of angular contact bearings, providing preloaded fixed-end support for the screw.
ALIGNMENT STAGE
Alignment Stage
Angular contact bearings support the screw drive of the XY stage, holding repeatability for micron-level positioning.
ELECTRIC CYLINDER
Electric Cylinder
Angular contact bearings at the screw end take the axial load, delivering smooth and stable linear thrust.
LASER ENGRAVER
Laser Engraver
Angular contact bearings at both ends of the gantry screw keep accuracy stable under high-speed reciprocating motion.

Quality & Collaboration
Product confirmation flow established around drawings, samples, application and delivery requirements, reducing selection and communication cost.
ENGINEERING REFERENCE
A clear technical starting point for selection.
The catalog's engineering reference covers bearing tolerances, internal clearance, vibration and noise, lubrication, and shield/seal classification. Actual selection also depends on model, load, speed, temperature and mounting conditions.
Tolerances & Precision
The catalog lists P0, P6, P5, P4, P2 precision grades and explains symbols for inner/outer ring dimensions, tolerances and runout.
Internal Clearance
Provides C2, C0, C3, C4, C5 clearance designations for thermal expansion, mounting and operating temperature.
Vibration & Noise
The catalog explains measurement and grading concepts by vibration acceleration and velocity; levels confirmed by product and test requirements.
Lubrication & Sealing
Covers grease selection, low/high temperature and humid conditions, plus Z, ZZ, 2RS shields and seals.
A clear collaboration path
Starting from your application, we confirm series, samples and delivery step by step.
01
Provide Application
Shaft diameter, speed, load, temperature, sealing and mounting space.
02
Confirm Series
Narrow the selection by product structure and use case.
03
Sample Validation
Technical confirmation by drawings, samples or test requirements.
04
Batch Delivery
Stable supply built around quality, packaging and lead time.
