The food and beverage industry depends on clean, reliable linear motion that can maintain speed and precision through washdowns, corrosive cleaning agents, product contamination, and nonstop production schedules. PBC Linear provides stainless steel linear motion products and optional FDA-compliant Frelon®W bearing liners for applications where corrosion resistance, reduced lubrication, and contamination control are critical. The examples below show how linear motion components help packaging and filling equipment stay productive in demanding food and beverage processing environments.
Food packaging bagging equipment
High-speed food and beverage packaging equipment needs linear motion components that can survive washdowns, shock loading, powder contamination, and limited lubrication without causing frequent downtime. In this example, a large Illinois manufacturer of automated packaging equipment was experiencing repeated failures in bagging machinery used for products such as cake mixes, where escaping powder, regular cleaning, and harsh operating conditions created problems for linear ball bearings and guideway systems.
The original linear ball bearings required lubrication and were not able to tolerate the combination of washdown, shock loads, and airborne product contamination. Bearing failures every 4–8 weeks caused unacceptable downtime on high-speed production lines. PBC Linear redesigned the box upsetter section of the machine using Simplicity® plain linear bearings, which required no lubrication, handled shock loads, and continued operating smoothly through washdown and powder exposure.
PSF flanged Simplicity® sleeve bearings were also used elsewhere in the same machine to replace a bronze bushing in a cam actuator that was failing due to dirt and dust contamination. The retrofit improved reliability across multiple problem areas, giving the customer smooth, quiet operation and longer trouble-free bearing life in a demanding food packaging environment.
Bottling equipment washdown system
Bottling equipment often operates in washdown environments where cleaning agents, moisture, and limited lubrication can shorten the life of rolling-element bearings. In this example, a bottling equipment manufacturer was experiencing repeated failures when washdown chemicals stripped lubrication from linear ball bearings, causing the bearings to seize on the shaft and damage both components.
PBC Linear recommended Simplicity® plain linear bearings as a self-lubricating alternative to linear ball bearings. The Frelon® liner creates a microscopic transfer film on the shaft, producing smooth Frelon-on-Frelon motion without external lubrication. The plain bearing design also helps wipe particles from the shaft during travel, reducing the need for seals in this application.
By switching to Simplicity® plain linear bearings, the manufacturer eliminated frequent bearing and shaft seizing, reduced replacement costs, and improved uptime in the washdown area. The result was longer bearing life, better shaft protection, and a lower overall operating cost for the bottling equipment.
