Bearings (Lubrication)

Health and Safety

• LOTO the machine

• Wear the appropriate PPE ( including gloves)

Lubricating the Linear Bearings ( each one or two weeks)

Check the quality of the lubrication on the guide rails every week to determine when more grease is needed. The frequency of greasing depends on many factors including amount of use and dust. After enough time has passed to determine a pattern, document how often the bearings should be greased, but continue to inspect the rails every week. Because the linear bearings require frequent lubrication and can be damaged by over greasing, MiTek recommends the following grease and grease gun be used. Grease Recommended Mobilux™ EP 2 This is a general purpose, lithium-based Grade 2 grease that provides excellent protection against rust and corrosion and resists water wash-out, corrosion protection, low temperature pumpability, and high temperature service life. Grease Gun Recommended It is recommended to use the following grease gun to ensure the proper amount of grease is applied. If you do not have this grease gun available, it is recommended that you purchase one for future use. Understanding the number of pumps to use (the output of grease) will extend the life of the bearings and the accuracy of the saw. Hiwin GN-80M Output: 0.5-0.6 cm3 per stroke If you choose to use a different grease gun, document which gun is to be used for this procedure and ensure employees know the output per stroke. The output per stroke should be equal to or less than 0.5 cm3 per stroke.

• Grease the Infeed Rail Gripper Bearings (as shown on the pictures)

• Grease Infeed Side and Top Clamp Bearings

• Grease Stroke and Elevation Bearings

• Grease Outfeed Clamp Bearings

Lubricating LASM Linear Module (every 24 months)

The LASM linear module should be lubricated every 24 months (one shift) Use a grease gun to apply 2.8 cm3 of grease to the fitting shown in the picture

• Grease the LASM Linear Module Location (5 strokes and a half)

Lubricating the Cam Followers (Outfeed Assembly) (Once every 12 months)

As a board exits the saw chamber, a set of cam followers make contact with the board’s back surface to guide it and ease its travel to the outfeed. Apply a #2 lithium-based grease to each of these cam followers once every year. Remove the top guard to access the cam followers.

• Grease the Cam followers

Lubricating Lumber Exit Chain Bearings (every 12 months)

Apply a #2 lithium-based grease to the idle-end bearings once every 12 months

• Grease The Lumber Exit Bearings

Lubricating Waste Conveyor Drive shaft (every 12 months)

Lubricate the waste conveyor bearings with #2 Lithium-based grease once a year. There is 1 grease fitting on each end of the drive shaft.

Lubricating Wheels ( every 6 months)

There are 2 drive wheels that drive the belts. Each of the drive wheels have 2 bearings with grease fittings on the front and rear side of the conveyor. Use a #2 lithium-based grease every 6 months The non-powered wheels that guide the belt require no lubrication. The conveyor rollers and skate wheels on the Skewed Conveyor require no lubrication

• Grease the Skewed Conveyor Wheels

Lubricating Chains (every 02 months)

The chains utilized in this machine may require cleaning, lubrication, or tensioning. This section details which types of maintenance are necessary for specific chains. These chains should be lubricated with a high-grade, non-detergent, petroleum base oil. Anti-foam, anti-rust, and film-strength improving additives are often beneficial. SAE 30 grade is recommended. Apply oil to the edges of the link plates of the chain near where the chain makes contact with a sprocket and to the inside of the chain generally.

• Remove yellow guard to access chain and sprocket. Lightly lubricate the chain every 2 months.
