30x50x20mm Bearing DE0678 deep Groove Ball Bearing DE0678CS12

Description

Product Overview

The 30x50x20mm DE0678 deep-groove angular contact bearing from CURMCZZF is a precision‑engineered component designed to meet the rigorous demands of modern industrial machinery. Constructed from high‑grade steel, the bearing features a deep‑groove raceway that distributes loads evenly, reducing stress concentrations and extending service life. Its compact dimensions—30 mm inner diameter, 50 mm outer diameter, and 20 mm width—allow it to fit into tight spaces while delivering exceptional radial and axial load capacity. The DE0678CS12 model incorporates advanced manufacturing tolerances, ensuring minimal runout and high rotational accuracy, which translates to smoother operation and lower vibration levels in high‑speed applications.

Key specifications include a load rating of 2,500 N, a maximum operating speed of 12,000 rpm, and a temperature range from –30 °C to +120 °C. The bearing is supplied with sealed steel shields that protect the internal rolling elements from contaminants such as dust, moisture, and debris, thereby reducing the need for frequent lubrication and maintenance. The product complies with ISO 281 standards and has been tested for durability under cyclic loading conditions, guaranteeing reliable performance in demanding environments.

Usage

This angular contact bearing is ideally suited for a wide range of industrial applications, including high‑speed gearboxes, spindle drives, precision machining equipment, and power transmission systems. Its ability to handle combined radial and axial loads makes it a versatile choice for equipment that experiences multidirectional forces, such as CNC machines, robotic arms, and conveyor systems. The bearing’s robust design also supports use in harsh environments, including factories with high levels of dust, chemical exposure, or temperature fluctuations.

Installation is straightforward thanks to the standardized bore size and the inclusion of protective seals. Users can mount the bearing onto shafts or housings using conventional press‑fit or clamp‑fit methods, and the sealed design eliminates the need for additional lubrication during the initial setup. For applications requiring higher axial load capacity, the bearing can be paired with complementary thrust washers or collars to further enhance performance.

Maintenance intervals are extended due to the sealed construction, but regular visual inspections are recommended to verify that the seals remain intact and that no external contaminants have breached the protective barrier. When used in high‑speed spindle applications, the bearing contributes to reduced runout and improved surface finish on machined parts, directly impacting product quality and production efficiency.

FAQ

What is the maximum speed this bearing can handle?

The DE0678 angular contact bearing is rated for a maximum operating speed of 12,000 rpm, making it suitable for high‑speed applications such as spindle drives and gearboxes.

Can this bearing be used in environments with high dust or moisture?

Yes. The bearing comes with sealed steel shields that provide protection against dust, moisture, and other contaminants, allowing it to operate reliably in harsh industrial conditions.

Is additional lubrication required after installation?

Because the bearing is sealed, it is pre‑lubricated and does not require regular re‑lubrication under normal operating conditions. However, periodic visual checks are recommended to ensure the seals remain intact.

What warranty does CURMCZZF offer for this bearing?

CURMCZZF provides a standard one‑year warranty covering material defects and premature wear when the bearing is used according to the specified guidelines.
