Semi-Precision? Semi-Ground? Functional Precision?

 

THESE ARE DESIGNATIONS THAT ARE OFTEN USED TO describe our 20000 inch series ball bearings.

Even though these bearings are not considered to be ABEC1, they are produced from 52100 chrome alloy steel, with all functional surfaces ground. This is just one of the product lines that General Bearing Corporation has built its reputation on.

The 20000 series provides an economical alternative to ABEC1 bearings. We offer bore sizes that range from .1875" to 1.3125". The bearings are offered as open types, two Buna N seals (-88) and two shields (-77). Certain sizes are available with snap rings. These bearings are dimensionally interchangeable with the popular Nice 1600 series.

Applications for these products are diverse. These bearings are found in food-processing equipment, exercise equipment, packaging equipment and even the motor homes we see cruising the highways.

Load capacities are similar to the ABEC1 products with a recommended speed level of 5000 RPM. Steel retainers are standard in our 20000 series. The inch dimensions help to keep costs down with the use of "inch dimension" shafting. The product is stocked in all of our warehouses, available for immediate delivery.
