How to choose Linear guides

Points to check when selecting, with the values for this product (LWL Series Linear Bearing (Roller Type EXSEV Linear Bearing)).

  1. 1. Select rated load from load and life

    This product: Basic dynamic load rating C 5970 N

    The basic dynamic load rating C is the basis for rolling life calculation. Estimate the load on each block, inertial force during acceleration and deceleration, and moment loads, then select a model number with a C that meets the required travel life. When using multiple blocks, also consider load distribution.

  2. 2. Allow margin for static load and shock

    This product: Basic static load rating C0 8440 N

    The basic static load rating C0 is a guideline for the limit beyond which permanent deformation of the rolling surfaces occurs during stopping or under shock loads. Secure a safety factor against the maximum load, and when moment loads are applied, also check the static moment rating.

  3. 3. Determine size series by rail width

    This product: Rail Width W1 5～42 mm

    Rail width W1 is the reference for the size series, and listed products range from 5 to 42 mm. Greater width increases load capacity and rigidity, but also increases mounting space and mass. Select an appropriate width based on both load conditions and the dimensional constraints of the equipment.

  4. 4. Verify assembly height and block width against drawings

    Assembly height H is the height from the mounting surface to the top of the block and directly affects table height and interference with other components. Block width W also affects the mounting space on the table side, so verify dimensions together with the block type (flange or block type).

  5. 5. Check rail length against required stroke

    This product: Maximum Rail Length 600 mm

    Confirm that the required stroke plus block length and allowances such as stoppers fits within the maximum rail length that can be manufactured. If it does not fit, also consider whether spliced rails are possible. Mounting hole pitch F is needed for hole machining design on the mounting surface.

  6. 6. Select material suited to the environment

    For cleanroom, vacuum, or corrosive environments, or equipment that must avoid magnetism, specifications using stainless steel or ceramics are options. Organize requirements for particle generation, lubricant evaporation, corrosion resistance, and non-magnetic properties, and confirm material and lubrication specifications.
