Product Features

7009 ACE/HCP4A INA Angular Contact Ball Bearings of Properties:

- In a closed environment with grease and oil
- Planter and plough discs
- Cutter bar
- Rotary harrowsProperties- Double-row angular contact ball bearing
- Open design
- Suitable for radial and axial loads

Due to their internal design, 7009 ACE/HCP4A INA Angular Contact Ball Bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing.

As previously mentioned, 7009 ACE/HCP4A INA Angular Contact Ball Bearingsare usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. This can bee done by matching up multiple single row bearings or by utilizing double row angular contact bearings which may offer some econmic benefits. However, utilizing multiple single sow angular contact ball bearings can offer greater design flexibility and performance in many cases.

Tremendous Selection of Angular Contact Bearings from INA Bearings
INA Bearings supplies more than 550 single-row, precision, Angular Contact Bearings in its online catalog with bores ranging from as small as 10.0 mm and as large as 280 mm. Standard contact angles of deflection include: 15, 20, 25, 30, and 40 with other custom angles available to meet special applications. Furthermore, ceramic and special SV30 stainless steel materials are also available to maximize performance.

Angular Contact Ball Bearing Series
Many angular contact bearing manufacturers have three or more dimensional series to accommodate higher speeds or higher loads than “standard.” In particular, the most common series names are:

ISO 18 Series - highest speed, lowest load bearings
ISO 19 Series - second highest speed, with the second lowest load bearings
ISO 10 Series - highest load, second lowest speed bearings
ISO 02 Series - highest load, lowest speed bearings
ISO Equivalents To AST's Series Designations

Bearing 7009 ACE/HCP4A SKF can support radial and axial loads. Able to work at higher speeds. The contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take 15-degree angular contact ball bearingsAngular contact ball bearingsIn the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, while the radial load, will cause additional axial force. And the only limit axial displacement in one direction, the shaft or housing. If paired installation, so that one pair of bearing outer ring relative to that wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit the axial clearance range in both directions.Angular contact ball bearing raceway for its inner and outer rings relative displacement on the horizontal axis, so it can bear radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, So often adopted installed in pairs).Cage made of brass, synthetic resins, etc., depending on the bearing forms, and application conditions.Angular contact ball bearings: 7000C type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) types. bearing outer ring locking in the general inner and outer rings can not be separated, can withstand radial and axial joint load and axial load in one direction. Axial load capacity of a decision by the contact angle, the contact angle is large, the ability to withstand high axial loads. This kind of bearing can limit the axial displacement in a direction of shaft or housing.
The main purpose
Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifuges, small car front wheel, differential pinion shaft
