This 3307A 2Z/C3MT33 bearing is a metric double row angular contact bearing with a metal shield on both sides of the bearing filled with lithium grease, a steel cage and a larger than normal radial internal clearance. The bearing's dimensions are 35x80x34.9.
Energy Efficient Double Row Angular Contact
Part of SKF’s new E2 energy efficient bearing range, with a minimum reduction in friction of 30% than standard angular bearings providing significant energy savings and improving service length. Further improvements in bearing life can be achieved with these angular bearings potentially running 5 to 30 °C cooler than the equivalent standard bearing under the same conditions.
Angular contact ball bearings are designed for applications where both axial and radial loads are present at high running speeds. In addition one double row angular bearing is more compact requiring less space than a matched pair of single row bearings. Optimal inner geometry means quieter and cooler running with a reduction in maintenance and build quality that exceeds the required standard promotes smooth running with less vibration and cooler running temperatures.
Double Row Angular Contact Ball Bearings are similar to Single Row Axial Ball Bearings (when used as a pair, back to back), however, unlike Single Row Axial Ball Bearings, they can accept radial and axial loads simutaneously.
3307-ATN9 SKF Double Row Angular Contact Bearing 35x80x34.9
Double Row Angular Contact bearings are designed to work as two single row angular contact bearings but take up less axial space. They can accommodate radial loads and axial loads in both directions. The bearings have a 30 degree contact angle with the ball sets arranged back-to-back. Cage material can be either metal (no suffix) or glass reinforced polyamide with the suffix "TN9". Double Row Angular Contact bearings are available in open design (no seals or shields) or with Metal Shields "2Z" and Rubber Seals "2RS1". The shielded and sealed bearings come pre greased with high quality NLGI class 3 grease with a temperature range of -30 to +120 degree C and are marked with suffix "MT33".
SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings
arranged back-to-back, but take up less axial space.
They can accommodate radial loads as well as axial loads in both directions.
They provide stiff arrangements and are able to accommodate tilting moments.
The standard assortment of SKF double row angular contact ball bearings
comprises bearings in the 32 A, 33 A and 33 D series.
Bearings in the 52 and 53 series are no longer available from SKF and have been replaced with 32 and 33 series bearings.
With the exception of size 3200, 32 and 33 series bearings are dimensionally interchangeable with bearings in the 52 and 53 series.
Size 3200 has a width of 14 mm instead of 14,3 mm.
