What is the difference between 6000 and d6000 bearings?

D6000/602847 bearing is a bearing produced by GRW, Germany. The specific information is as follows:

- Basic parameters: inner diameter 10mm, outer diameter 26mm, width 8mm; ball material is SI3N4 ceramic ball; bearing type is full ball angular contact bearing without cage; accuracy level is European P4 level and American ABEC7 level; single bearing speed can reach 156,000 rpm (up to 200,000 rpm when oil lubricated).

- Working conditions: The lubrication method is jet aviation lubrication while reducing the temperature. The temperature that can be tolerated is 300 degrees Celsius. The application conditions are short-term high speed and high temperature.

- Application field: It belongs to aircraft engine bearings and can be used in large flow flow meters and aircraft turbojet engines and other equipment.

Description

GRW Bearing refers to the bearings produced by GRW High Precision Ball Bearing Company in Germany. Here is an introduction to it:

Product Type

- Radial deep groove ball bearings: self-retaining, can run at low and high speeds, can withstand radial loads and a smaller degree of axial loads, and are available in open as well as sealed or shielded versions.

- Spindle ball bearings: single-row angular contact ball bearings with accuracy grades of ABEC 7 (DIN P4) and higher, contact angles of 15° (C) or 25° (E), with high running accuracy, strong axial load capacity and high speed.

- Double ball bearings: can withstand large loads and allow precise positioning, can be positioned very accurately in radial and axial directions, have consistent system deflection limits, and have higher load capacity than single ball bearings.

- Axial ball bearings: designed to withstand loads working along the axis of the shaft or body, consisting of a flat shaft locating washer with raceway, a flat housing plate with raceway, and a ball set with a steel plate cage.

- Special purpose bearings: can be developed and designed individually according to customer requirements to meet personalized needs in special environments.

- Precision bearing units: composed of single or multiple ball bearings, shafts or bearing seats, optional spacer rings, gaskets or wave washers.

Product features

- High precision: The precision level can reach ABEC9/P2, which can provide precise operating support for the equipment and ensure the high-precision operation of the equipment.

- Wide temperature adaptability: It can operate at extreme temperatures from -270°C to 450°C, suitable for extreme environments such as aerospace.

- High durability: The rings are made of ultra-long-life SV30 alloy steel, the balls are made of steel balls or ceramic balls, and the cages are made of reinforced fiber phenolic resin and other materials, so that the bearings have a long service life.

- Low friction: The advanced design and manufacturing process can effectively reduce friction, reduce energy loss, and improve the operating efficiency of the equipment.

Application areas

- Aerospace: such as satellites, space stations and space walkers.

- Medical field: dental/surgical handpieces, medical equipment, blood pumps, etc.

- Precision instruments: precision measuring instruments, encoders, etc.

- Industrial equipment: precision spindles, vacuum molecular pumps, special motors, high-speed galvanometers, etc.
