Technical Information

SUC insert limiting speeds

The limiting speed of any ball bearing insert is, for practical purposes, determined by the quality of fit between the inner ring and the shaft.

QCB Ref	Shaft tolerance

SUC 201	6700	5300	3800	1400

SUC 207	4000	3000	2000	750
SUC 208	3600	2600	1900	670
SUC 209	3200	2400	1700	600

SUC 212	2400	1800	1200	450

Setscrew tightening torque

The 2 setscrews should be tightened to the appropriate torque figure. Over tightening may result in a fracture developing in the inner ring.

Should the axial load be high, a small dimple in the shaft may improve the locking effect, but beware of introducing unwanted stress concentration factors.

For best axial load carrying capacity the bearings should be mounted against a shoulder in the shaft.

Materials

QCB® Stainless Steel bearing units are made in high quality stainless steel for maximum corrosion resistance.

All pillow blocks and flange units have a solid base and smooth exterior surface restrict the growth of bacteria.

Food Grade Lubricant

QCB® Stainless Steel SUC inserts are lubricated with MOBIL FM 222 grease

Under normal operating conditions, the suggested relubrication intervals are tabulated below (ndm = average diameter x rpm)

ndm value	Environmental conditions	Temperature	Relubrication interval
< 40 000	Clean	-15 to +65 °C	6 – 12 months
		+65 to +100 °C	2 – 6 months
< 70 000	Clean	-15 to +65 °C	2 – 6 months
		+65 to +100 °C	1 month
Any	Dirty / Water splash	Any	1 month

Operating temperature range

QCB® Stainless Steel inserts can operate in environments from -30 to + 120C
