(Overrange/margin requires both 'From' and 'To' values to work.)

Help with Ball Splines specifications:

Specifications
   Overall Shaft Length:       The overall length of the shaft including length for mounting. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Inner Race Length:       The overall length that the ball nut is allowed to travel in a straight line, before returning to its original position. Inner race is the term used to describe the groove the bearing balls ride in. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   O.D. Spline Shaft Diameter:       The largest overall diameter of the shaft. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Spline Nut Overall Length:         
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Spline Nut Outer Diameter:       The maximum outer diameter of the ball spline nut. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Static Torque:       The maximum thrust load that can be applied to the ball nut in a stationary position. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Dynamic Torque:       The maximum thrust load that can be applied to the assembly which will result in a pre-determined minimum life of travel. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Mounting Options
   Mounting Options       
   Your choices are...         
   Pin or Set Screw       Suitable for applications with low torque requirements. 
   Key and Pin       For applications with high torque requirements 
   Square Spline nut       The spline nut can be directly installed on a machine body. 
   Geared Flange Spline Nut       Gear teeth are cut into the outer flange of the spline nut. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features
   Hollow Shaft?       Useful for piping, wiring, or relieving compressed air. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Hollow Shaft Inner Bore Diameter:       The inside diameter of the shaft. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
