Sanitation is a number one priority in food safe production environments. Even the smallest amount of rust or corrosion on equipment can result in regulatory fines or downtime. Preventing rust and corrosion in extreme environments, which are often humid and subject to high pressure hot water cleaning with strong chemical agents is challenging. We design, develop, and manufacture industrial telescopic slides for these environments. Below is an example of a washdown unit made of corrosion resistant stainless steel materia

Roller Bearing Linear Guides provide high capacity with the least amount of deflection under load while offering low friction guidance of payloads for machine applications. With 4 rows of recirculating rollers engaged in a precision ground rail, these bearings provide load capacity in all directions. Industry standard sizes 25 to 55 High load carrying capacity Very little deflection under load resulting in high stiffness and rigidity Rail lengths to 4000mm with splicing available for longer lengths

We design, develop, and manufacture custom curved linear rail guide systems for medical, industrial, and mobile vehicle applications. Below is an example of a system that we designed for a food packaging machine. It provides a means to transport pouches in a controlled manner along an oval track to various fill and seal stations. The track radius 225mm (8.8 inches) with 1200mm (47.2 inches)long straight sections. Up to 40 moving blocks can be utilized to move product along the rail.

The Minibot is a family of actuators built around industry standard linear bearings and motor frame sizes. The linear bearing options include wide versions of size 7, 9, 12 and 15 linear bearings. Standard motor frame sizes include NEMA 11, 14, 17 and 23. Actuator stroke is selectable by the mm up to 500 mm of travel in the larger sizes with various leadscrews and ballscrews available. Overall, this flexibility enables the Minibot to be configured to deliver the load capacity, speed, and precision your instrument application requires.

We now offer straight, 90 degree turn, and 180 degree turn sections as standard off-the-shelf items for those who wish to build their own systems. For OEM applications we will make "custom" rail units. Click on the picture below to go directly to our online catalog.

The SBI ... H Series High Temperature Linear Guides provide high load capacity and precision guidance like the SBI Series but are modified for high temperature environments. The Aluminum end caps enable all metal construction. Suitable for temperatures up to 180 °C (356 °F). Industry standard sizes 15 to 65 Load capacities from 4.5kN to 320kN (1000lbs to 72000lbs) Rail lengths to 4000mm with splicing available for longer lengths Special surface treatment options are available such as Raydent, TDC, and TDNC

The MR Series Miniature Linear Guides provide precision, low friction guidance of payloads for machine and instrument applications. These bearings have 2 rows of recirculating balls engaged via 4 point contact to a precision ground rail which provides load capacity in all directions. Industry standard 3 to 15 sizes and 2 to 15 sizes in wide format rails Load capacities to 12kN (2800lbs) Rail lengths up to 1000mm available Options for seals, scrapers, and maintenance free lubrication system Stainless Steel construction for corrosion resistance

These bearings are usually found in application such as: wind turbines, heavy load transporters, solar trackers, harbor cranes, hydraulic equipment, crane steering mechanisms, automation systems, heavy load manipulators, yaw and pitch control tables.

Used to connect two shafts together at their ends for the purpose of transmitting power, shaft couplings alter the vibration characteristics of rotating units while allowing for further mechanical flexibility. They also offer protection against overloads while reducing the transmission of shock loads from one shaft to another. Our superior line of shaft couplings are easy to both connect and disconnect and can transmit full torque power from the driving shaft to the driven shaft without any energy losses. Used for servo and stepper motor systems, our shaft couplings are both corrosion resistant and antibacterial treated, making them ideal for medical equipment. They are also packaged for clean room applications. Available in a wide range of configurations, including miniature shaft couplings, bellows shaft couplings, and torque limiting couplings, we offer an array of shaft couplings geared to meet your particular application needs.

Thin Section Ball Bearings were developed for applications where space limitations are most important. They have an extremely small, predominantly square cross-section. Within each series, the cross-section remains constant giving them the unique desciption as a constant section bearings. There are basically three types: deep groove radial contact, four point contact, and angular contact. We offer the four point contact type since these are most popular and can support axial loads from both directions as well as radial loads; they thus act in the same way as double row angular contact ball bearings
