Reduce Costs, Streamline Production, Support Design Innovation
with Custom Bearings
#DWwebinar
q How to compare standard and custom bearings for the most cost-effective solution
q Why custom bearings are not always cost prohibitive q Design innovations that are only possible with a custom
bearing q How you can use custom bearings to reduce costs and
streamline production from design to supply chain management
Overview
#DWwebinar
q Carry loads heavier than necessary q Are capable of speeds in excess of
need q Are manufactured to tighter-than
necessary tolerances q Are manufactured from a few
standard bearing materials
Standard Bearings:
#DWwebinar
q More expensive than necessary q Unnecessarily complex q Over-sized q Constraint to design innovation
Over-specified Standard Bearing
#DWwebinar
Bearings Basics: Foundational Considerations
#DWwebinar
q Bearing type q Loads and speeds q Operating environment
The Bearing Selection Process

#DWwebinar
q Thrust bearings are designed to carry primarily axial loads
Identify the Bearing Type
#DWwebinar
q Radial bearings are designed to carry radial loads
Identify the Bearing Type
#DWwebinar
q Angular contact bearings are designed to carry both radial and axial loads at the same time
Identify the Bearing Type
#DWwebinar
Plain Bearings – no rolling elements
Define Loads and Speeds

q Carrying capacity in excess of requirements? q Requiring a change in the size or shape of the mounting,
mating components? q Ability to eliminate or reduce number of components? q Is the lifecycle of the bearing greater or less than your
product’s lifecycle? q Large minimum order quantity?

#DWwebinar
Integrate Additional Features
Over-molded Radial Bearing
Eliminate Components in your assembly q Addition of a threaded stud for
mounting q Simplify installation process q Reduce purchasing and
inventory costs
#DWwebinar
Integrate Additional Features
Stamped Angular Contact Bearing
Integrate More Exotic Features q Include a ratcheting
mechanism q Integrate cam arms for spin
control q Change manufacturing
process from machining to stamping
#DWwebinar
q Stainless Steels- 300s, 400s, 17-4 q Engineered Plastics- Nylon, Delrin, Acrylic q Ceramics – Si3N4, Al2O3 q High and Low Carbon Steels q Bronze and Aluminum q Exotic Materials – Titanium, Nitinol q Protective finish – Plating, Passivation, Anodize
Proper Material Selection
#DWwebinar
q Alternative materials can stand up to tougher environments
q Protective coatings can resist corrosion q Proper material selection can remove the need for
additional seals

Supply Chain Strategies for Additional Cost Savings
#DWwebinar
Packaging Solutions q Standard bearings have multiple layers of
packaging and boxes q Require time-consuming removal of
bearings from layers of packaging q Create large amounts of packaging waste
#DWwebinar
Packaging Solutions Custom bearings can be package in custom trays that: q Present bearings, properly oriented and ready to
assemble q Reduce amount of packaging waste q Reduce shipping and inventory costs
#DWwebinar
Packaging Solutions Bearing Tray Redesign Yields $25,000 in Annual Savings q New tray design increases bearing
capacity from 12 to 16 bearings q 30% Less boxes and trays equals
30% fewer pallets q Customer reduced number of
pallets to ship by 30% q Realizes a savings of $25,000 in
shipping costs
#DWwebinar
Kanban .
#DWwebinar
q Reduce amount of inventory required q Reduce minimum order requirements q Allow for smaller shipment of USA made bearings q Dramatically reduce lead time
Kanban
#DWwebinar
q Standard bearings may be an effective solution q Custom bearings can reduce costs, streamline
production, support design innovation q Know how and when to compare the options
