6214-2Z/C3 Deep Groove Ball Bearing 70x125x24mm Double Metal Shield C3 Enlarged

1. Product Overview

6214-2Z/C3 is single row deep groove ball bearing with double metal dust shields and C3 enlarged internal clearance, standard metric dimension 70mm inner bore × 125mm outer diameter × 24mm width.
Model Code Explanation:

• 6214: Medium light series deep groove ball bearing, matching shaft diameter 70mm
• 2Z: Double sides non-contact stamped iron dust shield, block dry dust and solid particles
• C3: Enlarged radial clearance, reserved expansion space for high temperature and high vibration operation

Inner ring, outer ring and steel balls adopt GCr15 high carbon chrome bearing steel, integral quenching and mirror superfinishing raceway process. Stamped low carbon steel cage evenly separates steel balls to reduce collision noise during high-speed rotation. Double non-contact iron shields form dust barrier without extra friction loss, suitable for dry dust workshop environment. C3 extra clearance eliminates bearing jamming caused by thermal expansion of motor spindle during long-time continuous operation. The bearing can bear bidirectional radial load and small axial load simultaneously, stable low-noise operation. Widely applied to three-phase asynchronous motors, industrial fans, belt conveyors, textile machinery, agricultural equipment, water pumps and all high-temperature vibration transmission equipment.

2. Technical Specifications

Mounting dimension drawings, motor assembly matching guides and high temperature continuous rotation durability test reports can be provided on customer request.

3. Core Advantages

1. C3 enlarged internal clearance design, effectively compensate thermal expansion of shaft and bearing ring under long-time high-speed heating, avoid bearing clamping, abnormal heat and premature failure for motors and fans.
2. Double-sided 2Z non-contact metal dust shield, block dry dust, fiber debris and metal powder, good dust-proof performance without increasing rotational friction torque.
3. Smooth superfinished deep groove raceway, ultra-low friction coefficient, stable low-vibration low-noise running performance for long-term continuous motor operation.
4. Stamped integrated steel cage, light weight and small centrifugal loss under high speed, not easy to deform under frequent start-stop circulation.
5. Standard unified metric interchangeable dimensions, fully compatible with global mainstream 6214-2Z/C3 motor bearings, direct replacement without modifying motor shaft and housing.
6. High hardness quenched GCr15 steel raw material, strong anti-fatigue and anti-spalling capacity, long service life under cyclic vibration load of textile and agricultural machinery.
7. Pre-filled long-life anti-wear lithium grease inside shield cavity, realize maintenance-free operation under dry clean workshop environment.
8. Rich customizable options: 2RS rubber contact seal upgrade, P5 high precision grade, food grade grease filling, OEM laser marking on outer ring, neutral export anti-rust carton packaging.
