Original HIWIN Linear Guide Rail 15mm EGH15SA Guide Block
TAIWAN HIWIN offeres two type blocks of flange type and square type, 15 mm Medium load (SA) square type block EGH15SAZAC block mounting from top, these linear blocks can install with the EGR15R or EGR15U (large mounting hole M4*16 and mouting from top)linear guide rail. the rail lenght can supply200.2 mm to 4000mm each piece. also if needs the length of more than 4000mm, we can provide the joint sevice to meet your request.
Please notat that the first hole of rails (E dimensions will be the same at both ends unless otherwise specified in the purchase order). Also for the rails accuracy we have C (Normal), H (high), P(High precision) in stock, for the accuracy details, please kindly check within next page of Pdf file (G-Interchangeable-Accuracy-Grade).
The design of the EG series offers a low profile, high load capacity, and high rigidity. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation machines and applications where space is limited.
The retainer is designed to hold the balls in the block even when it is removed from the rail.

HIWIN guideways are supplied with a coating of anti-corrosion oil before being shipped. Please clean the oil before moving or running the blocks.
Recognition of master and subsidiary rails: For non-interchangeable type linear guideways, there are some differences between the master rail and subsidiary rail. The accuracy of the master rail’s datum plane is better than the subsidiary’s and it can be a reference side for installation. There is a mark “MA” printed on the rail. Check for the correct order before starting the installation. The rail number of master is an odd number and the rail number of subsidiary is an even number. Please install the rails according to the indication and carry on the installation according to the order for multi-rails installment (e. g.: 001 pairs 002 ; 003 pairs 004 etc.)
Recognition of datum plane: The datum plane (B) of rail is the side indicated by the arrow, which is marked on the top surface of the rail. The datum plane of block is smooth ground surface which shows as D in Figure 2.
Butt-joint rail: Butt-joint rail should be installed by following the arrow sign and ordinal number which is marked on the surface of each rail as shown in the figure 3. To avoid accuracy problems due to discrepancies between the 2 rails such as for matched pair, butt-joint rails, the jointed positions should be staggered as shown in figure 4.
Do not remove blocks from rails when assembling the guideways in machines as far as possible. Please use block inserts (please see Figure 5) if it is necessary to remove/ mount block from/ onto rail.
Please do not randomly mix block units and rails for non interchangeable type to avoid any installation problem.
To ensure the straightness of rail, please tighten the mounting bolts sequentially with a torque wrench to the specified torque. (Refer to HIWIN Technical Information).
