Closed-shell stainless steel plain linear bearing pillow blocks are mountable linear bearing assemblies designed for food and drug handling equipment, washdown applications, corrosive environments, and other machinery requiring corrosion-resistant, oil-free linear motion. They use stainless steel housings with inserted stainless steel plain bearings and self-lubricating liners. The closed-shell design is used with end-supported round shafts where full shaft enclosure is preferred during linear travel.
PBC Linear closed-shell stainless steel pillow blocks use an inserted FL or FLC Simplicity® plain linear bearing rather than a liner bonded directly to the pillow block housing. The inserted bearing has a 316 stainless steel shell with a bonded, self-lubricating FrelonJ® liner that provides oil-free, maintenance-free linear motion. The straight-bore housing is non-self-aligning and is recommended for single-shaft applications where alignment is established by the machine structure.
FrelonJ® is supplied standard for operation with 300-series stainless steel and softer shafting such as aluminum. The bonded liner performs in extreme temperatures, dirt, contamination, vibration, shock loads, corrosive environments, and washdown applications, making these pillow blocks especially suitable for non-contact food and drug handling equipment. For potential direct food-contact applications, go to Configure to choose the optional FDA-compliant FrelonW® liner.
Precision and compensated ID options are available. Precision bearings provide 0.0005" running clearance per side for a tighter fit, while compensated bearings provide 0.0015" per side for additional running clearance. Closed-shell stainless steel pillow blocks are available in inch sizes from 0.5" to 2" ID, with four pre-positioned mounting holes for standard-sized housing installation.

Frequently Asked Questions
When should a closed-shell linear bearing pillow block be used?
A closed-shell linear bearing pillow block is used with end-supported round shafts where the bearing can completely surround the shaft. For continuously supported shafts, an open-shell pillow block is generally required to provide clearance for the shaft support.
Why use a stainless steel plain linear bearing pillow block?
Stainless steel plain linear bearing pillow blocks provide corrosion resistance for washdown, chemical, humid, and other corrosion-sensitive environments. They are also well suited for non-contact food and drug handling equipment when configured with the appropriate bearing liner.
Is FrelonJ® suitable for food and drug handling equipment?
FrelonJ® is suitable for non-contact food and drug handling equipment as well as washdown and corrosive environments. For applications involving potential direct food contact, choose the optional FDA-compliant FrelonW® liner.
What is the difference between FrelonJ® and FrelonW®?
FrelonJ® is designed for corrosion resistance, washdown environments, and non-contact food and drug handling equipment. FrelonW® is the FDA-compliant liner option for applications where potential direct food contact must be considered.
Do stainless steel plain linear bearings require lubrication?
No external lubrication is normally required. The bonded Frelon® liner is self-lubricating, allowing the plain linear bearing to provide oil-free, maintenance-free linear motion.
What is the difference between precision and compensated linear bearing clearance?
Precision bearings provide 0.0005 inch running clearance per side for a tighter fit. Compensated bearings provide 0.0015 inch running clearance per side, adding running room where additional clearance is desirable.
What shaft materials can be used with FrelonJ® linear bearings?
FrelonJ® is designed for use with 300-series stainless steel shafting and softer shaft materials such as aluminum. Shaft material, hardness, surface finish, and operating conditions should be considered when selecting the bearing and shaft combination.
Are closed-shell stainless steel pillow block bearings self-aligning?
No. These stainless steel pillow blocks use a non-self-aligning straight-bore housing and are recommended for single-shaft applications where proper alignment is established by the machine structure.
Can stainless steel plain linear bearings operate in dirty environments?
Yes. The self-lubricating Frelon® liner can operate without oil or grease that may attract contaminants, making these plain linear bearings suitable for applications involving dirt, debris, vibration, and other harsh operating conditions.
