The important thing to take care of is the bearings. So, once they are dry, apply oil just like sewing machine oil. The oil will help in smooth functioning. Also, oiling will help in the long life of the bearings.
Roller bag wheels and bearings collect dirt over time, reducing their performance and slowly eroding the bag's basic functionality. To clean them, you'll need to remove the wheels and push out the bearings. Typically, this can be done using a screwdriver. Once extracted, clean the bearings using a cloth.
A rolling suitcase is inherently wobbly because the force we apply at the handle is misaligned with the wheels. Suitcase handles are inside of the wheels, so when luggage gets perturbed — by a bump or sudden turn — the handle pulls the suitcase inwards.
Spinner suitcases are more about agility. Having wheels on every corner gives you 360 degrees of motion, which makes them great for zig-zagging through crowds and turnstiles at check-in and security.
Spinner luggage is more susceptible to breakage because the wheels move in different directions. This is especially true when you're rolling over uneven surfaces like cobblestone. The wheels on upright luggage, on the other hand, tend to be more durable because they don't move around as much.
Spinner Luggage is the classification of upright luggage with telescoping pull handles and four wheels on the bottom of the case, when the case is positioned vertically. However, some of the manufacturer's have used the dual-caster wheel.
A simple way to guard against scratches and dings is to buy a protective sleeve to encase your bag. There are a slew of products to choose from, ranging from clear plastic sleeves to patterned fabric wrappers, and luggage manufacturers such as Hartmann are getting into this game.
Luggage Wheel Materials
Luggage roller wheels are typically made of polyurethane (a highly-resilient flexible plastic), other plastics, or rubber.
The suitcase rolls behind you as you pull it from the extending handle. Pros: Wheels are recessed, which protects them from snapping off during rough handling. For city trips, two-wheelers are better than four-wheelers for clearing curbs and rolling on uneven surfaces, such as sidewalks or cobblestones.
“Almost all U.S. airline crew members use soft-sided roll-aboard bags,” Patrick Smith, airline pilot, air travel blogger, and author, tells Reader's Digest.
Since the wheels spin around, they can easily get caught in bumps, cracks, and really anything not super flat. For example, you'd never roll your spinner around upright over cobblestones or rocks, they'd likely break off. And, if you pull a spinner at a slight incline, then you're likely to cause damage.
The pros of spinner suitcases
On flat and even surfaces, spinner suitcases are arguably easier to roll, as there's less friction, and less pressure on your arm and shoulder. Spinner suitcases are often hard-sided, which some prefer, as it's potentially more durable, and protects the items in your bag.
Wheels: 2 Wheel vs 4 Wheel
A 2 wheeled suitcase has to be pulled behind you, which tends to be easier if wheeling on rougher or uneven surfaces. 2 wheeled cases are good for those on a tighter budget and are usually lighter and offer more internal capacity than a 4 wheeled case.
Sadow, the former vice president of a Massachusetts luggage company. Sadow's design allowed travelers to no longer have to carry a heavy suitcase by the handle. Rather, the Rolling Luggage — as Sadow patented it in 1972 — sat on top of wheels and could be pulled around the airport by a strap.
Re: Carry On Bags - Do the Wheels Count? To answer your question: wheels do not count.
Of those, over 252,700 were reportedly mishandled, meaning roughly one in every 100 bags was lost, damaged, delayed, or stolen. Overall, Allegiant Air had the fewest mishandled bags, as well as the second-fewest enplaned bags, of the 10 major carriers, followed by Hawaiian Airlines and Frontier Airlines.
If you're using a lock that isn't approved by TSA, agents have the authority to break open that lock to search through a bag. If you're carrying your valuables with you in your carry-on bags, and you don't have anything really valuable in your checked luggage, then you may not need to use a luggage lock.
