Screw Conveyor Hanger Bearings

Hanger Bearing Styles Style 216 Hanger Bearing Style 226 Hanger Bearing Style B Hanger Bearing

Hanger bearings provide a bearing surface to support a screw section when multiple screw sections are used in a screw conveyor. Hanger bearings are journal or plain type bearings that mount in hangers and are replaceable when worn. Many different hanger bearing materials are available, depending on the application. Style 216 and 226 bearings are the most widely used and are in stock at KWS.

KWS hanger bearing recommendations are listed in the Component Series Table of the KWS Screw Conveyor Engineering Guide for the specific bulk material to be conveyed. The most common hanger bearing materials are described in the table below. Please consult KWS Engineering for specific hanger bearing recommendations.

Bearing Material	RPM Max	Temp Max (°F)	Wear Resist*	Industry Uses	Comments
Nylatron (NR)	60	180	3	Chemical handling, grain, feed	Self lubricating, very low load capacity
UHMW	60	160	6	Food, Ice	USDA approved, doesn’t swell in water
Gatke (G)	75	250	7	Medium temp applications (alternate for Hard Iron)	Low load capacity, Food Grade
Hard Iron (H)	75	400	9	Lime, Cement, Salt, Gypsum	Requires hardened shaft, can be noisy, lube req’d in some applications
Wood (W)	175	160	4	Grain, Feed, Fertilizer	Self lubricating, good general purpose
Plastech (P)	100	160	6	Grain, Food	Food grade
Bronze (BR)	150	850	7	Grain, Feed, Processing	Self lubricating, high quality bearings, high load capacity
Ball Bearing (BB)	400	180	1**	High speed, low loading	Screw action tends to force product thru seals reducing bearing life
Stellite (S)	50	1000	10	Very high temp applications, metal processing, ceramics	Requires stellite insert in shaft

* 0 = Least, 10 = Highest ** Depending on bearing type and seal arrangement

Hanger Bearing Styles

Style 216

Style 216 hanger bearings are used in 216, 316, and 230 hangers, and are manufactured to CEMA dimensional standards. Style 216 hangers and hanger bearings offer superior rigidity and are excellent for extra heavy-duty applications.

Style 226

Style 226 hanger bearings are used in 226, 326, and 220 hangers, and are manufactured to CEMA dimensional standards. Style 226 hangers and hanger bearings have clearance for bulk materials to pass and are excellent for normal and heavy-duty applications.

Style B

Style B hanger bearings are used in 660 and 670 hangers, and are manufactured to CEMA dimensional standards. Style B hanger bearings utilize a self-aligning ball bearing for lower power consumption and quieter operation. The bearing is sealed to minimize contamination.
