polypropylenenitrile rubberstainless steel

Product overview
The stainless steel hanger bearing units SHA series are designed for suspended shaft support in conveyor and material handling systems, providing a hygienic design and low maintenance for food, pharmaceutical and other demanding industries.

Advantages
The units include an adjustable, pre-lubricated AISI 440C stainless steel ball bearing. Bearings can be re-lubricated via an AISI 304 stainless steel grease nipple or a quick coupler. Units accept a safety cap in polypropylene or AISI 304 stainless steel. Optionally available: a rotary shaft seal ring (TC) with extra dust lip in NBR rubber and a stainless steel spring.

Usage
The SHA mounted hanger bearing unit supports suspended shafts in conveyors and material handling equipment. It ensures smooth shaft rotation, reduces friction and improves load distribution for long shaft spans and continuous operation.

Industries

• Food processing — for screw conveyors and auger systems; resistant to high-pressure washdowns
• Pharmaceutical — for sterile material handling and cleanroom use
• Beverage — for conveyor systems in bottling and canning lines
• Chemical — for bulk material transport and mixing systems exposed to aggressive chemicals

Material & Construction
Constructed from AISI 304 (AISI 316 optional) stainless steel with smooth, polished surfaces to meet hygienic standards (EHEDG, 3A). Units can be fitted with food-grade seals and high-performance stainless steel bearings to ensure corrosion resistance and reliable operation.
