1.  In the case where Nabtesco confirms that a defect of the Product was caused due to Nabtesco’s design or manufacture within the Warranty

Period of the Product, Nabtesco shall repair or replace such defective Product at its cost.  The Warranty Period shall be from the delivery of the
Product by Nabtesco or its distributor to you (“Customer”) until the end of one (1) year thereafter, or the end of two thousand (2,000) hours
running of the Product installed into Customer’s equipment, whichever comes earlier.

2.  Unless otherwise expressly agreed between the parties in writing, the warranty obligations for the Product shall be limited to the repair or

replacement set forth herein.  OTHER THAN AS PROVIDED HEREIN, THERE ARE NO WARRATIES ON THE PRODUCT, EXPRESS OR
IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE.

3.  The warranty obligation under the Section 1 above shall not apply if:

a) the defect was caused due to the use of the Product deviated from the Specifications or the working conditions provided by Nabtesco;
b) the defect was caused due to exposure to foreign substances or contamination (dirt, sand etc.)
c) lubricant or spare part other than the ones recommended by Nabtesco was used in the Product;
d) the Product was used in an unusual environment (such as high temperature, high humidity, a lot of dust, corrosive/volatile/inflammable gas,

pressurized/depressurized air, under water/liquid or others except for those expressly stated in the Specifications);

e) the Product was disassembled, re-assembled, repaired or modified by anyone other than Nabtesco;
f ) the defect was caused due to the equipment into which the Product was installed;
g) the defect was caused due to an accident such as fire, earthquake, lightning, flood or others; or
h) the defect was due to any cause other than the design or manufacturing of the Product.

4.  The warranty period for the repaired/replaced Product/part under the Section 1 above shall be the rest of the initial Warranty Period of the

defective Product subjected to such repair/replace.

Features

Maximum ease
of use

(1)  The hollow construction allows cables to pass through the reduction gear.

(2)  The servomotor shaft (input shaft) is positioned at a right angle to reduce

the height from the base.

(3)  RS series gears can be installed with servomotors for most manufacturers.

(4)  All RS series gears are provided pre-greased.

(5)  The use of a specialized input spline and motor fl ange means motors can

be easily attached and detached.

High reliability
High rigidity
High precision

The double-end support design and unique pin gear mechanism provide the

following advantages:

(1)  Capable of fi ve times the rated torque (Emmergency stop)

(2)  Demonstrates extremely high resistance to twisting (torsional rigidity)

(3)  Achieves minimal backlash (1 arc.min)

(4)  Produces a high torque density from a small body

Heavy load support

A set of internal main bearings (large, angular ball bearings) provides complete

support of heavy external loads.
